In some cases, like Halo: TMCC, I'm glad that a compilation was made. With others, like Devil May Cry, I sit and get bothered by the laziness of teams. Coming up with new IP is hard and expensive, so they just add HD textures, maybe have a few little chunks of DLC (unless you're Turn 10, then you release a GotY game with no Season Pass content included), and pretend that it's what the fans have been dying for. This generation could get turned into an ugly nostalgia-fest, between game streaming with old titles and all of these remakes.
Did Metro really need a remake? I got it because I heard that the games are good, and I play it for about 30 minutes, get bored, and try again a week later. Devil May Cry 4 was good, but not some kind of amazing game I feel needed brought up to the new generation. Halo, on the other hand, is a flagship franchise that's a decade old and had content (Halo 2 online) missing from the last generation (well, when they took the original Xbox LIVE servers down). Gears of War, I'm on the fence with. I never played the fourth game, so if it's part of a remake, I'd be interested, but I don't have much care for it, and if it's not included, I will be disappointed.
New IP, that's what I want. I feel sorry for Black Tusk, since they had their actual project delayed and/or canceled to work on the Gears series. I guess it'll economically benefit them, but it still sucks. I'm much more interested in The Division and Dying Light than the remakes of all of these franchises (other than Halo).
