is it going to be something like a bowser base game like runescape?

It will not be a browser game. It will require a client (like EQ, WOW, COH, etc...)

I like how when chris lists games he lists EQ first. maybe this games mechanics will be more like EQ than WoW for once. I would be so happy if thats true.

I am happy that he mentioned City of Heroes! Since I spent roughly 3-3.5 years of my life on that game.

All other mmo's I have played have not lasted longer then... a few days to 3-4 months. Heck, with a very few exceptions, most singleplayer games don't last me longer then anything from 1 day to 3-4 months... which makes CoH a very unique game for me.

I seem to remember quite a while ago, it was suggested the game engine would be made/ based on the Earthrise engine by Masthead Studios?

They are currently working with masthead studios that have developed Earthrise and the will probably use the same engine if I remember right.

What type of game, well is going to be an AWESOME game

hoping for a Story based MMO personally.
