It "seems" that Microsoft is trying to market to the casual audence moreso than the hardcore audience this Christmas. I keep seeing X360 ads with the whole Star Wars LCS/GH3 ads as opposed to ads for shooters.
Juding by the casual and Core game sales (Simpsons game, NFS, Viva Pinata, Scene it?, ect), it seems to be working, as Scene It has it's 3rd week of increased sales.
Having said this, you can aruge "oh, the X360 doesnt have a RPG basis" from games that did bad like Blue Dragon and Eternal Sonata, but the WRPG base is really, really strong. Two Worlds did pretty well on the Xbox 360 despite recieving sub-60% scores. Oblivion had mammoth legs. Why not Mass Effect?
ME will still hit 2m worldwide. I guarentee it.
Back from the dead, I'm afraid.
