[casual_games] browser based game engines

[Miguel Portilla]

Unity seems to be a great engine, especially considering everything you 
get for the price. The problem we had with it when we were evaluating it 
was that it's really geared towards 3D games and not 2D. The latest 
version added some support that helps with 2D games, but it can use 
more. We've encouraged the Unity developers to improve that, even given 
them a 2D feature wish list. Sure its possible to hack out a 2D game 
with Unity, but it's not a clean comfortable development path. I 
sincerely hope future versions will improve the 2D capabilities, 
especially since 99.9% of casual games are 2D.
