Dawn of War -- Help?

[Natalya]

Okay so like 4 years ago when Wh40K Dawn of War was released for the PC, I was one of the first people to buy it. However, at the time, since the game was new only a few people actually played in the online mode, so I soon lost interest and went back to playing Star Craft, until I got CS:S... Anyway, now I've gotten interested again, and have re-installed Dawn of War, but there have since been 3 game updates... Winter Assault, Dark Crusade, and Soulstorm. These updates combined cost more than the original game itself, and don't seem to even need the original which I have anyway.

So, I was wondering if anyone could explain which one(s?) I need to get to have everything set up properly.

I've not played 'em online yet, but I'm pretty sure all you need is just DoW to play online.

Right but hardly any1 plays the vanilla online anymore. They all got expansions n' stuff.

*ponders* well, the platinum edition (with DoW, DC, and WA) runs for 'bout $30 now... and Soulstorm is $40... if you sell off your original DoW, then the cost is only as much as an A-list console game.

(and after checking the box, yeah, I'm pretty sure you need DoW for WA, but not for DC [but I could be, and probably am, wrong])
