I beat Demons Souls last night! Sorry, had to tell someone as my girlfriend struggled to the grasp the magnitude of my heroic accomplishment.

The Japanese really comes out in that ending... shades of MGS.
Funny thing is, that I have 3 games in my backlog. All of which I have played an hour or so: ME2, Singularity, LA Noire. And I want to do, is play NG+ on Demons Souls, which is crazy, as I can't even remember the last RPG I enjoyed, or finished; I have tried Oblivion, Fallout 3, Borderlands, etc.
Anyway, really pumped for Dark Souls now. The items on my wish list are:
-keep the non-scalable enemies.
-keep co-op... I think voice would be ok in co-op. I know some think it would ruin it, but I wouldn't mind it, you could always turn it off. But definitely no voice for Invaders, it is already lame enough to get invaded, killed, then get a message saying 'U R teh Sux0rs. Loser.'
-keep combat the same, simple... yet deep.
-allow me to sell shit I don't need.
-i don't want the level-up girl to give me that
"You seek soul powa? For thine is the kingdom, the powa and grory, forever and ever..." ever time I want to level up..., not to mention that little spiel after leveling up..
-for all the talk of an open world in Dark Souls, I hope that is something lost in translation. I really don't feel like a GTA style open world. DS was overwhelming enough, I find open world games overwhelming because of all the options available to you at once, I often find they feel like work to me.
-this talk of Dark Souls being even harder worries me. I found the second 75% of Demons Souls to be not that hard, but 1-1 through 4-1 were killer. The early difficulty just made me appreciate my newfound powers that much more though.
As I make this list, I realize that what I really want is just more Demons Souls
