    So I decided to better explain this with a video. And I will state it again, the best games in this space are low key, low risk hobby projects. If you go the big AAA route with a big budgets and shine a spotlight on yourself and force players to utilize centralized servers you will be sued into the ground and probably face all kinds of negative consequences. If the game fully follows regulations then it will turn most people off from wanting to play because they wont want to pay taxes for stuff they don't even actually own. Furthermore centralized games offer similar degree of ownership and avoid all of these negative aspects.

    This is a super interesting topic but I seriously think most people who are just now getting involved are stepping into a complex situation they don't actually understand. Etherlinker is a great plugin and can be great for doing small projects or just getting ETH as a potential side payment method. Centralized servers and big budgets are a super bad idea regardless.

    HOWEVER I do see a great use of blockchain to store players and characters data in it. Though even for for inventory for a multiplayer game it would be too low throughput. maybe the core stats and status of the character. or the money count. But still.... there must be some server that can add or remove the money count based on in-game events.
    Yep I am fully aware of the fact that the blockchain isn't fast enough for everything. That's why you make use of checksum hashes to make it very hard to hack the client with the ability to generate valid transactions. Its the only method you can do off chain actions without a need for a centralized server. Storing player data is an ok thing and you can use it for some stuff like that, but the dev here has already explained that etherlinker is not designed to store data on the ETH chain. Its only good for microtransactions or moving tokens around apparently.

    Also, ETH 2.0 is proof of stake and will be able to handle thousands of TPS. EOS, TRX and STEEM among many other much faster coins.

    In the context of gaming, nobody is going to play your game if they have to pay taxes for their pokemon pets or trading cards. Nobody is ever going to want to deal with that level of complexity to enjoy a video game. Period. They will continue playing centralized games rather than deal with that. That is 90% of your potential audience instantly lost the moment they have to write down exactly how many dudes they killed on the way to the level cap. Its not even fun at that point its work.

    Incorrect, you need to be doing your research, there are various games most of which are card games or JRPGs. Gods unchained, Steem monsters, EOS Knights Axi Infinity... The space is constantly growing. But like I already stated, the ones that use centralized servers are not going to survive, nobody is going to play a game where they get a massive bill from the government because they played it. You either go decentralized like the medium dictates or you get crushed by those who do.

    This space fundamentally requires decentralization. If you do not understand this then get out of this space because you are about to get rekt hard. The idea that you "Own your items" is a lie and decentralized infrastructure can only be taken advantage of with decentralized mediums. That means decentralized games or bust. If you sit anywhere in between on this you are massively hurting your chances long term and probably risking massive fines and potentially jail time.

    The only games I can ever see working in this space are going to be low key indie games with anon devs. Gambling dapps and maybe the occasional strategy or turned based JRPG. Anything else is massively risky. I am having a super hard time seeing blockchain gaming going mainstream. Its not worth doing with a oldschool mindset.

    Centralized servers means that you have a single point of attack. So when FBI/CIA agents bust down your door because some butt hurt bureaucrat made online monopoly money illegal you can let me know how it was such a good idea to take advantage of that immutable decentralized transaction service like ETH using your centralized servers. So much for those centralized servers eh, also welcome to being in jail for not having a money transferring license or whatever weird potential **** that might come down the line.

    Honestly, when it comes to building in this space it makes far more sense to keep the games fully on chain and be anonymous if possible. This goes double depending on if you live in a country where the government is highly likely to try and tame the beast. Trumps lapdog Mnuchin made it very clear he does not want people even talking about bitcoin in the next 5 years.

    A crypto based game with centralized servers is like a horse and carriage running with a diesel engine that can explode at any moment.

    You have no idea how many of my problems you solved with this plugin A big thank You! And its good to know it will be further developed.

    I will try to add support for it when it will be available and as soon as all required libs(like web3j) and services/apps (infura/geth/parity) will start to support it.

    Kind of reminds me of the crypto market as a whole. The potential to use this kind of stuff is great but very few will ever actually do it.
    I will though, my goal is to get absolute baseline support in place so I can move on from there. NEOS online is a VR game that does literally everything I wanted all at once and supports ETH now too which is kinda insane.

    Apparently the steem blockchain responds to JSON commands without any need for crypto implementation too...
    Slowly but surely people are coming around.

    Hmm, what about just searching all previous transactions and confirming that one exists with the following memo sending X amount to a specific wallet? If I have to manage an array like you say then that would mean having to have some kind of server right? Or do you mean an array that is on chain? The DRM can be used where in a multiplayer game everyone's client checks everyone elses client to see if its legit. Thus everyone playing would need to have hacked clients to play.

    I wonder what kind of publicity something like this might get. I have a couple projects right now that I can consider doing this with.

    It's possible (you don't need any specific values, just add wallet address to the game owners array in smart contract after buying), but I guess it's still will be hackable because if the player has access to the PC memory, where the game is located, he could change everything if he has enough skill (for example, simply ignore your DRM checks). Another solution is to make a multiplayer game, where the only server has the authority to do everything, including DRM checks. Even then, I guess it could be possible to hack some parts of your game (otherwise there wouldn't be any cheaters in multiplayer games).
