3d - iOS Game Engine Choice -

i'm new ios game development i've worked bit on ios apps , had fair share of objective-c. have concept game planned out i'm not sure if i'll need 2d engine or 3d engine. closest example can give how possibly-3d part of gameplay clash of clans, there buildings 3d, never turn around them or anything, see people or character walking between them possibility of zooming in , out , panning. i'm kind of inclined use cocos2d since seems easy , documented want worth @ end, won't limit me someday if want create proper game or expand 1 i'm working on.

so should go 3d or 2d development , engine or development environment should go if so?

if don't know if you'll need 2d or 3d engine, definition game concept not planned out. ;)

whether need 2d or 3d you.

if worry limited game engine, pick 1 that's open source. way can make changes yourself. though should not overestimate time , effort required make changes engine, because requires intimate knowledge of inner workings of engine.

i have more general advice picking game engine here. best advice pick engine you can productive rather picking engine based on feature set - unless have requirements absolutely non-negotiable (such 3d rendering).
