Tournament, anyone?

No Oric, if Vicious doesn't want to play IG, Necrons or Tau he's fine; you don't need the expansions to play against people with those races.

We can also get around the problem of Relic servers by using Hamachi, so even those without the game can download/torrent it if they wish and join in (I am in no way condoning piracy).

You cant play on the normal game against those using WA and DC.
