Some of the comments on this thread are simply baffling. So just cos a game is free it means it's crap or it shouldn't be allowed into the stores? Just who the heck you people THINK you are?
You know, some people make games cos they genuinely like it, if you are pissed that a free game is taking attention from a paid game, then make better paid games. :)
The moment you get greedy is the moment you lose all creativity and taste for what you do. You needn't go too far, look at the gaming industry, all cookie cutter crap games, originality just flew out of the window and it's RARE these days, when in the old days originality and passion was what games were made of and it's what got them to where they stand now.
Onto the topic... I do think the limitation is complete crap, the price it's alright if you are serious about making money with games and have the money for it, cos let's face it, these companies can't give two craps about you or yer financial stability. So AppMobi it's pretty much only for people that have the resources, which is yer typical corporate greed. We are surrounded of it, sadly.
