UE3 vs UE4 vs UDK
I don’t think its as Black and White as the others make it seem, not for UDK which I use.
A lot has to do with a dev’s skills. If in doubt, look at CobaltUDK / Coldscooter projects!
Plus UE3 has been licensed in recent years. The price varies But think low-5-figures!
Editor runs on Win32, UE4 Editor doesn’t (many 7-10 year old PCs stuck on Win32).
UE4’s minimum spec is around GTX-670m, whereas UDK runs like a beast on that!
Bugs are mostly all known by now. Its very stable, hardly any crashes or they’re rare!
Simpler to learn. Kismet is far simpler than BP, same goes for Unrealscript vs C++!
Its friendly as a modder engine: Lots of Vehicles / Weapons / Characters to Mod etc.
Simpler Asset-Management and smaller project footprints because its older system.
Kismet supports Get & Modify-Property to tweak Unrealscript, great for prototyping!
No updates / fixes. So any roadblocks, you must find your own workarounds or bust.
No source, and Kismet is often obfuscated along with a lot of key Unrealscript etc!
While simpler to learn, Kismet is too simple and Unrealscript too limited w/o source!
Often slated as being FPS only (but RPG / RTS / Space-shooters are common also).
Source… If you or your team have the C++ chops, then literally anything is possible.
Looks beautiful. Everything across the board is a notch or two better looking in UE4.
All the editors are well designed and they’re getting better all the time if you’re patient.
Geared to a vastly increased number of ‘gametype possibilities’ than UDK / UE3 etc.
Complexity: Its a tough beast to tame. Maybe 2/3 times harder then UDK & 4/5 Unity.
Source control is pretty much mandatory and overall file / project sizes are far higher.
BP is easy, but its also limited and draws on OOP, so parts may confuse non-coders.
C++ is considered easier than vanilla C++ but requires use of outside tools unlike uc!
UE4 min spec is about GTX-670m, this is bare minimum for Editor & Design anyway.
Lots of change all of the time, every version. So stability / predictability can be tricky.
For modders? … Not a lot of Vehicles / Weapons / Characters to Mod out of the box.
Some devs are extremely unhappy with the Physics system especially for car games.
Updates, fixes, PR’s are backlogged. AH support posts go unanswered. UDN is key!
Missing killer features: Large-Worlds / Spherical-Runtime terrain / Better Landscapes.
No Kismet Get & Modify-Property equiv for tweaking C++ source, full C++ or nothing!
