Dino Crisis. Certainly would be great if they remade that. But I do worry that it would not be the same game after they would have to dumb it down and butcher it for current audiences.
That and I also remember enjoy Parasite Eve.
There is rumours of them wanting to bring back Dino Crisis, last year Capcom Dev 1 posted asking people if the people wanted it back then they might bring it back.
Remastering games or porting them to a different platform will still cost a lot of money in development/testing resources
You thinking big AAA titles like Skyrim. A lot of these games are really small for example Dino Crisis is only 600mb. That means the sound and texture files are pretty small, repeated a lot to make the game.
If they wanted to remastered that game, turning the textures into higher resolution isn't really a problem, fans do that all the time, fanpacks are available for a lot of games. Audio will be a little harder and more expensive.
Regarding Dino Crisis again, there is already a patch that does a lot what HD remake does, fixes glitches, fixes and increases performance, adds modding tools, adds support for new computers and gamepads, widescreen fixes and all done by one guy.
This happens a lot in Japanese games, games without English support are often fan supported and released by a small team, in the last few years, these small teams are being legally hired for official releases.
There is a few games on Steam that have been remastered and are selling for £25-30.
AAA titles wise, take the recent example of Resident Evil and Resident 2 remakes, they selling that for a full £35-40 and that's going to sell bucket loads.
The real problems if they wanted to do it the correct way is finding the source code and if it's still available and possible the IP and even then it doesn't stop it, back to some recent Japanese games being brought to the West with English releases, the source code has been unavailable or denied to the western team and they been forced to pretty much hack it.
IP wise, well, since the games have been abandoned, the chances of someone making a complaint can be slim.
