yes a7 com is still a better choice maybe but if u compare unity free edition with lite-c edition both no cost but unity free has a lot more.
but lite-c is still good you can use plugins win api etc. not bad at all. sure the render to texture feature would be great too, and some other options of a7 com and pro.but unity looks actually more professional and good documentation too. in the next weeks and moth the community will explose in count of member which brings a lot more knwoledge etc. I I'm sure conitec and other competitors (and community members) will react. this reminds me a little bit of the browser war hehe and the result is today we have good browsers so let the engine war begin hehe
