Its true. That game belong to the same people of w.o.tanks. i domt believe u need a new machine. I have the last version and my machine is a dualcore 2 g ram. True about good internet speed.
but the point is, this type of game has not nothing to compare to cfs2 or 3. Heavier grafics but always external sight like a arcade game. Litle realism i think, but great fun! Lot a fun because u play against humans beings, not predecible A.I.
If i would be u, i would give it a try.
This is my thought.
Btw, i 've reached higher tier ( level) without expend a cent.
