I purchased ARMA 1 on the day of release and couldnt play it for 6 weeks, the game would crash on intro everytime, after 2 patches 6 weeks later the game would load but was useless/unplayable, I further 6 weeks and 4 patches later I finally got my first go on the game I was so angry with bohemia.
I again bought ARMA2 on the day of release thinking nah they wont do that again, and they didnt I could load the game I could play the game, but oh my god what a load of pap, the FPS where slow on my I7 and GTX295, the controls where clunky, and gameplay was horrible, the graphics where poor the story line was poorly put together and other than that this all made the online experience terrible in return, again ARMA 2.....another game sat on my shelf I shouldnt have wasted time or money on and pirated it.
Dont get me wrong I havent played OF2 yet, but come-on it cant be any worse!! Infact I'm pritty confident from what I've read and seen it will be a cracking game SP wise and quite fun MP wise, and lets not forget it'll be patched shortly and all you 32 player fanboys will no doubt comming running back. As for cancelling pre-orders the SP alone will be worth £17 you will have paid more for worse, idiots!
