Been playing for a while, offed a warboss, love the thunder hammer/jump pack combo, and really love the plasma weapons.
My old 40k army was Daemonhunters, but I never had anyone to play against (same problem I run in to with Brikwars, actually) and now the new codex is out and they're all weird. Not sure if there'd even be a place in the new one for all my Inquisitorial Stormtroopers.
If I had unlimited funds, though, I'd totally collect Forgeworld Death Korps of Krieg. They have the best looking armor for their basic troops. I've always liked the great coat/gas mask look, and they carry it off quite well.
Several of my friends from my old college days picked up SM, so maybe we can do some multiplayer; I get the feeling that's where the longevity will be for the game, much like it was for DoW2 until they killed Annihilation matches.
