I'm not really worried about Opflash2 yet at this point. There are so many cool addons and mods out already for this game, and with scripting, the missions type posibilities are endless.
I've been playing MP ever since the US version came out and nothing else I've tried can replace its realism. BF1942 was ok, but once you've played on such huge islands as there are in opflash, those BF1942 islands are pretty tiny.
Even with all of the great features the first one has, there are plenty of improvements I'm hoping for in OFP2. Too bad M$is the reason for the delay.
