It is hard but I thought maybe just the games I play the most and have kept up with ever since I ran into them, I haven't 1CCed DDP yet but I'm getting close to beat the 1st loop (I know, I suck) sometimes I prefer Donpachi over DDP but I feel DDP offers the better challenge, DP is hard though, haven't cleared it yet but I'm also close, closer than DDP. Both games are pretty much hand in hand as my favorites 'cause for the longest time Raiden was my favorite shooter but DDP has taken that mantle and not just right away, it took me time to appreciate DDP, I was a total DP and Batsugun guy and hated DDP and all the new wave of Danmaku, I felt the feel of DP was more in tune with the games I loved but after a while I warmed up to the Danmaku or BUllet Hell or whatever the right term is. I don't preffer one over the other, I like both and I feel DDP although Danmaku it still has that feel of the older games, I love it, plus the system is awesome, the combos are fair unlike DP where it's so hard to build a decent combo. DDP is not like DP where your bombs refill when you beat a stage...kinda good and bad but I'm happy it isn't, it would make the game too easy.
...As for NG3 NES well, that game has it all for me (I didn't find some of the cut scenes so hot but that's irrelevant in my case) and I've played the bejesus out of it ever since release and I'm not at the point of doing speed runs, well pass the 1CC, just trying for a NO Death RUN, one I'm past that then I'll start playing for score. The game has so many ways of being approached, it's my favorite platformer, Ninja Spirit came close to take the spot but I didn't run into Ninja Spirit 'till later in my life and I'm still green, it has more atmosphere of feudal Japan and what have you but NG3 just took the edge because although Ninja Spirit plays amazing, NG3 is just offers the better challenge and experience, tremendous music, amazing stages, excellent layouts, I'm just amazed at the game every time I play it and that's where the fun truly lies for me. I can see in the game how the concept of platforming was already mastered but they wanted to set the bar even higher, the concepts of platforming combine with the graphics just really worked, it gave the game both ambiance and challenge, I know this isn't the first game to implement such terrains in platforming but I feel it was a very creative entry in that aspect.
Super Street Fighter II X: Fighting is my favorite genre, most of us started before fighting games, even in the arcade and I understand what was lost once SFII came around but it not only revitalize the arcade scene, it created a phenomenon, a new way to play games, a new way to approach them. The VS genre took off to new heights unseen in video games, it brought back the very archaic concept of VS gameplay, like Pong did with a space management vs game, that's what fighting games are. I know it's a crazy comparison but it makes sense to me. Anyway, it could have been Fatal Fury Special...it could have been many others but I feel my choice is the premier choice of all fighting games, the ultimate version of the beginning...
