These announcements were more exciting in a "I can't believe this, ppl are gonna flip out" way than a "FINALLY, I've been waiting so long" way for me. Like these will probably good and I'll play them, but I have no personal investment in any of these three games. I wasn't waiting for them, I just spent a lot of internet time with a lot of people that did.
I can't even think of a nostalgia game that would excite me like that. Most of the games I loved as a kid are either ongoing, don't need to be brought back, or were brought back and were just ok/sucked. SFIV and MK9 are like the only exceptions (maybe Sonic Generations too).
