IMO there're two critical things that are missing:
- Spine support (fully featured, with skins, etc.
- Multiplayer support (Photon Cloud, it has become an industry standard)
'Serious' game developers can't use game engine if it doesn't fully support Spine, it's an industry standard, we can't avoid it. Multiplayer support is also pretty mandatory.
Currenly we have partially working p2p multiplayer support via Google Play Services, but there're few essential calls that are missing (for example 'leaveroom()'). And it's pretty painful to work with Google Play console, some time ago when I was testing p2p multiplayer, it took many days to make it work.
And Google's multiplayer doesn't work on iOS, that's an unsolvable problem.
We also have 'NoobHub' server, that is suitable only for card games or chess, where bad latency can be tolerated.
'Gideros Unite' is for local multiplayer only.
I'm in no way trying to blame maintainers, they did huge amount of work, it's a miracle how dramatically Gideros changed during last year, it's really miraculous. I'm subscribed to Corona&Defold updates, they didn't change as dramatically as Gideros, though they have full-time devteams hired.Guys if somebody else here is missing Spine and Multiplayer, can we crowdfund it?
If not, personally I have only two options - stick to what I know and have already, and focus on releasing few simple games withot stuff that I was planning.
Another option is to join the flock - switch to Unity, not because I need their bells and whistles and crap asset store, but because it supports everything out of the box, all the game services, analytics, Spine, Photon, etc. Unity is a plague.
Or maybe check Cocos2d-x, if their C++ API is as scary as some people say.
Please tell what you think about it.
