TR from the start. What I liked about it?
I actually read the lore before choosing and read the play style. Being the official government, lots of bullets, and the red and black.
Was a 60 gunner when I was in the military, taught booby traps, so the lots of projectiles interested me.
Black = Sin
Red = Redemption
This meant something personal to me.
Met lots of cool ppl, got TK'd a few times, but most wanted to just have fun. Have been in a few outfits, but mostly go off and do my own thing ( too busy to play regularly now ).
When I tell ppl about planetside, I tell them to join TR or I'll have to shoot them.
All in all, my favorite game!
