Played the demo. Good game, definately an improvement. Gameplay is more fluid, music is better, sounds are better, and looks better. But, I dunno hoe, but the voiceovers are WORSE than Arma1. They said in the GDC confrence when the original (Arma1) were used in the game, and the BIS guy laughed and said "don't worry, the voices will be much imporoved in the final version... I think not. BIS are seriously not delivering "The ultimate war sim". Ever since the breakaway from CM, they have been suffering, and it shows. Finance shows through the lack of engine optimisation. They actually had to release Arma1 before it was 100% because they needed money quick. Half the game has just gone to the dogs. Sure, CM are bringing OFP2 into a slightly different direction, but they have their act together. BIS should get with a well renowned publisher. They have tens of small time publishers for some reason...
Hopefully, they pull the Arma1 card where they bring out a load of patches and eventually polish and optimise the game to an enjoyable level. Then the community can take over and make it the game it should be (just like what Acemod did to Arma1) but the community won't be there forever... Perhaps a brand new engine, with improved physics, gameplay, modability and better optimisation (they called the Arma2 engine brand new... see for yourself).
Rant over. Sorry, just had to get that out.
