Really Additicting

There are a lot of mobile games that i want to play, but dont want to shell out $7-$10 to but them. I wish there were more demos or trail versions available.

I want to play the God of War mobile and Orcs and Elves, along with Doom RPG.
 
There's also a Kingdom Hearts mobile game that I'd like to try out.

It looked pretty good, but yeah the price is rather steep. However, if your often bored and only have access to your phone it comes in handy to have a good game, especially during your lunch break at work, or when your on the bus.
