Have been playing a LOT of Mount and Blade: Warband.
If you played POTBS it is for you. If you ever rode a stick horse as a kid. It is for you. Like Warhammer Fantasy? It is for you. Ever do SCA or period re-enactment or Ren Faire? It's for you. Ever play computer games and chase down other players and zap or shoot or hit them with a shovel? It is for you. Ever want to be a knight or a Cossack or a crossbow sniper or a Viking or just about any middle ages military type? It is for you.
Honestly it is the high water mark for gaming for me. If GW could do something similar with their IP then I would be just plain giddy.
As it stands I am just plain giddy up.
Local solo play: You start as a dude and enter a well designed sand box to do what you want. Want to be a bandit. Be one. Want to be a noble Lord or Lady? Be one. Anything in between those two? It is there for the taking.
Internet Multiplayer: Drop in a game for fun chaos or join an online regiment for fun, player generated events and good conversation on vent.
DLC: More internet multiplayer madness with the same engine but with during the the wars in the time of Napoleon.
Seriously. With the game and the DLC both it is 29.99 on Steam or at GameFly and no monthly fees to play. Dollar per dollar I see it as the current champ in computer gaming.http://www.taleworlds.com/
