Not trying because it "might" not work, gets people no where, in life there are risks, and rewards, take no risk get no reward. That is the way of life.
I bought it as it looks like fun, i'm not good at most games, i dont judge games, as i cant make a better product, i think of all the work the people that make the game put into it, then think hmmm thats alot of work, and i bet they are proud, i play for fun, and thats all games are. Sources of entertainment.
So before you pass judgement, look a bit deeper, and think a little, it might just make you appreciate the things in life we take for granted.
