l0rdtr3k: thing is,R$100 limit CC,so I'll have to weight the options on what to buy
DoW1 complete +DoW2 for example,R$67
Sachys: dark crusade wasn't bad (the necrons were quite interesting to play) but the game began to focus more on multiplayer and less on campaign / story.
Aside from adding in some new factions, soulstorm was pretty much more of the same and felt soull-less. Still, if they're dirt cheap, worth a look
l0rdtr3k: Take a look at this :
DoW Complete Collection £13 is $22. Not bad for 4 games at once.
Even better is the Ultimate Collection (it has also DoW 2, Chaos rising and Retribution) but I can't find it at a nice price right now. (I got it at 15€=$20.5 last year)
As you can see I'm a fan of the series..... If I would order them from best to mediocre it would go like this:
Dark Crusade (Best because you can choose battles, you have Honour guard and big map planning)
DoW 2 Retribution (Planetary destruction man!!!)
Winter assault (more intense from the 1st, more challenging battles)
Chaos Rising (same as DOW2, can continue with previous stats, can turn to chaos side)
Dawn of war 1 (only because its graphics are old, good story though)
DoW 2 (Different game, more tactics with unit squads)
Soul strom (a boring repetition of Dark crusade. Positive: 2 races more.)
