Actually I would rate it four and half stars.
This game was originally on the Xbox 360 platform, and it was regarded as
one of the best game of all time on 360. Gears of War also showcased what
‘next-gen’ gamings is all about.
They have done an exellent job bringing Gears of War to PC. It uses updated
UT3 engine resulting in better graphic than 360 (as long as your computer can
handle it), plus keyboard and mouse control feels natural, and don't forget
about new chapter exclusive to PC with an amazing boss battle.
However, it seems there are some problems with the game. Some people are
experiencing game crashes when starting the game using DVD launcher (in menu
screen). Also some people are experiencing stuttering issues, as well as
save/checkpoints dissapearing problems.
Dispite those problems, this is still an excellent game even after a year
from original release. New multiplayer maps and mode is another bonus! If you
like hardcore action shooter, try this game!
