Played this yesterday 4 player (the old GW version, not the new one).
I can thoroughly recommend it to anyway, its great fun, very silly and fast paced.
Each player has to try and make battle lines of orcs, goblins and the like and attack each other's line and steal their loot. Sounds like many other games, but its not. Lots of silliness from different cards, abuse being shouted from sneaky gits being placed in your line.
Its one of those games that hard to explain, but if you like 4 player fast paced, fun and silly games then give it a try.
You don't stop playing games when you get old, you get old when you stop playing games.
