From what I've read, they are working on graphics and textures ME2 and ME3 play fine, but I suspect they will roll on ME1 to bring the gameplay/firing/powers more inline with the latter two games.
They also said that all DLC content, weapons and armour will be included as standard. Which is awesome as I never got the chance to play any of the ME2 dlc.
Cannot wait to romance Tali and Liara again and kill off Kaiden the bore.
Yeah an upgrade of ME1 to the 2/3 system would be excellent and streamlined, especially the inventory as I recall it was a bit over the top.
To be honest some of the ME2 DLC was hit and miss, the character ones (Katsuni and Zaaed) were great the others not so much. but it is still the whole tale in one place.
bye bye Kaiden lol. My hope are that the new game is a true successor in the spirit of being a new trilogy/saga to follow your character over multiple games, I'm guessing Andromedda has been left behind.
