SimonG: It does in no way affect me as a player that chosen not to participate to buy stuff. If EA is making a few more bucks of that, fine with me.
Porkdish: I've read that its not uncommon to be kick voted from games if your gear or class isn't up to snuff. A user generated pay wall!? its interesting stuff.
I've read that if you screw a goat to often, it might get overly attached.
I've never been kicked from an ME 3 game. All three players need to agree on the kick, the only persons getting kicked are those who don't ready fast enough.
And all of the ME 2 DLC were either excellent (the stories) or completely superficial. I bought them to support the game, but never used them because they were worse than what was in the game.
