Flashpoint rocks. It's a good thing that the game is getting old, which means that you can get it really cheap nowadays. A couple of months ago I bought Game of the year-edition which has all the add-ons included, such as Red Hammer and the Resistance add-on. All this for a mere 17 euros.
With Resistance you even get better textures so it even looks a bit better than the first. Another thing about Flashpoint is that it has some excellent modifications such as the Finnish Defence Forces mod & Wargames, which make it even better.
BTW: I read somewhere that Bohemia Interactive is currently busy making Flashpoint 2.
