For example if you purchase soulstorm by itself through steam. You may go to skirmish and play ANY race you wish, however, when you click on multiplayer the races to choose between are limited to: Dark Eldar && Sisters of Battle.
If you purchase the other expansions plus the original copy then you can play all races (room for error). This is a major buzz kill because the game is fun.
In the original game, without expansion packs (Warhammer 40,000: Dawn of War), you have the option to play as the Orks, Space Marines, Chaos Space Marines, and Eldar. If you add the expansion pack "Winter Assault" (requires Warhammer 40,000: Dawn of War or one of its standalone expansion to play) then you gain access to the Imperial Guard. The standalone expansion, "Dark Crusade" (does not require Warhammer 40,000: Dawn of War, or Winter Assault to play, but you can only access armies which come with the game) 2 new armies, the Necrons and the Tau, are added. Finally, in "Soulstorm" (another standalone expansion which doesn't require Warhammer 40,000 or any of its expansions to play) adds the Dark Eldar army and the Sisters of Battle. Warhammer 40,000: Dawn of War is stand-alone. Its expansions, Dark Crusade and Soulstorm, are also standalone (Winter Assault is NOT standalone and requires the original Warhammer 40,000: Dawn of War game or one of its other expansions to play). However, you only get armies that you pay for. For example, buying only Dark Crusade and Soulstorm provides you with only the Necrons, Tau, Dark Eldar, and Sisters of Battle. You cannot access the Eldar, Space Marines, Orks, or Chaos Marines, who require Warhammer 40,000 original to play.
Nope, you will need a credit card to buy the WOW expansions.
The Roman army was crucial to Rome's expansion because without the army there could not be any expansion. Most of Rome's expansion came through conquests and an army was necessary for this.
No, you only buy it if you want to play the expanded core like getting to new maps. I say it's still good without buying expansions.
You do need a hard drive to download expansions, but the system won't turn on if you don't have a hard drive, so if you can turn it on without problems, and can play games then you definitely have a hard drive and you are able to download expansions.
No, the Shivering Isles is not written into the original version of the game. You can go there if you get the Shivering Isles expansion on a separate disc, the GOTY version includes both official expansions.
You can't. If you want to install any expansion packs, you need to have the Sims base game installed otherwise the expansions won't work.
if by oblivion you mean the elder scrolls then no, the game of the year edition is the original game and the expansion packs all on one disk, either way it is the same game besides the fact that the game of the year edition has both expansion packs on it, the knights of the nine and the shivering isles.
No. If you mean by patches, then yes you can. But not if you are talking about expansions. you have to buy it. My friend currently plays wow because I got on my account and downloaded the expansion and stuff to his computer under my account for free. That's one of the tricks I do to get people to play wow :)
Vanilla means from the original game, so the game without expansions or mods. Vanilla World of warcraft means everything that does not include the expansions. A vanilla World of Warcraft boss would be onyxia
No, you have to have either the Late Night expansion or the Supernatural expansion (which is not out at this time).
Not sure which Sims you mean, do you mean the original game, Sims 1? You need the first game The Sims installed and then you can install expansion packs. It is recommended by Maxis that you install The Sims first (expansions wont work anyway without it) and Makin Magic last.
