Uh, lets see here, kind of a big list.
Megaman Legends 3-----I've been waiting for this crap for eternity and it seems like it'll never be made, and never a finished story to what Rock does to get off of Eden I think it was.
Megaman 9----There's a DIRE reason I think me and many other fans of the blue bomber wish to see this. The Greek/Roman numeral X is stated to represent 10, given that would imply that Megaman 9 would be the prequel to Megaman X, how Doctor Light dies, how megaman X is made, along with Zero. Damn it why don't they do it?!
I don't remember seeing it in the lists here but The Final Fantasy 7 remake. I can play old sprite Final Fantasy's because for sprites they were done well. But when I look at FF7 as it is now, or the possible advent to new story content, I mean come on EVERYONE KNOWS what happens!
Ninja Gaiden 2--In the following of this game which I love, there only seems to be repeated releases of 'extra content' of the original which gets me to wonder 'Why don't they just put that toward making a sequel?'
Jak 4, I love that series to death. The ending to number 3 left a few plot holes and problems that made me go 'Wait what?' And there's tons of chances for more stuff.
Kotor 3, honestly tell me one person who played the last two that isn't fucking eager to see how the Exile and Revan take on the True Sith?
Speaking of Kotor, would it be too out of Topic bounds for me to ask that the lost content of Kotor be released on XBOX 360 or something there of? I know Team Gizka and Team Bantha are working on it, but I don't know if they can truly live up to Obsidians great story line and character interaction.
