Dial up will work for WoW.. You will however not be able to do anything with 20+ Players, You may beable to get away with 10mans. Satalite vs Dial up.. It's a Lose lose, Hughesnet you can raid, With minor lag (Non peak hours) Dial up you can do Arena's / Solo / Small Partys way better. So its a toss up on how ya wanna play.
Yep, dialup.. It's slow and not really reliable but that's how I've been playing WoW for quite some time now. I can tell when I goto StormWind or some other big city as it lags some, but since I do mostly solo questing/leveling it mostly works out okay. Tony
