Any advice for a total noob making a 4X game?

Give up. Like, right now. XD Just for the time being.

Completely forget about making a game that requires a studio for right now. Seriously. In the future after you have quite a bit of experience then you can start worrying about it but for right now concentrate on learning the basics. I’d suggest blueprints, since C++ has a steeper learning curve. You can find those tutorials anywhere at this point. It’s not that bad, just practice-- a lot.

My suggestion is to challenge yourself to make some simple games that require a decent amount of knowledge. For example, make one or two 2D games, mario/sonic clones with more stuff, for instance. Then take it further and create some target shooting game (3d, ofc) with particle effects you created on your own, your own art assets, that kind of thing. Then move further into making some sort of local (or online if you feel up to it) fps arena game. That should give you the basics behind AI. By then you should be more than acquainted with UE4. That kinda thing is what I would do, anyways. It’s up to you. But it’s too early to be thinking about making a game like that as of now.

Good luck :3
