I'd still be interested to know how many people have done BotB on more than one platform, though. There must be some, because it's not possible that a scrub of my lowly level can be the only one.
I'm sure there are, but I don't actually know of any. When I bought an Xbox I kinda assumed I'd go for the banner again, but when the reality of promoting hit me I decided I'll be an N7 120 over there for as long as the game is still playable.
I found doing an Insanity playthrough of both ME2 and ME3 on Xbox was masochism enough, given my personal difficulties with the controller. Man, that Collector Ship in ME2 is tough if you can't land headshots. I made the mistake of doing it with an NG+ character too, which increases the difficulty even more because the enemies are scaled beyond your own upgrades. By comparison, when I played ME3 on Insanity on PS3, the only times I died were either down to the Reaper on Rannoch, or some bloke called Marauder Shields - I think it took me 7 attempts to get past him and his Husk friends, so in some senses the 'final boss battle' in ME3 is strangely appropriate. I'm not wishing to open up any sores for anyone on that subject - just talking about gameplay.
