www.trygames.com and cracking
 

note, thats no warez.

Those are full games but with time limit, and u register them after that period to keep playing. Now, regular cracks don't seem to work, so I need suggestions.

Simple: If you like it, then buy it.

Are these games really full games or just the demo version.
How does this work? How many days can u play till u have to register?

Like ByteMare said : Like It, Buy It.
