I'll list them in the order I bought them.
Super Mario 64 - 9/10
I really don't know what prompted my to get this. I already had the N64 & DS versions. But, then again, it's a fantastic game, so why not buy it again? XD
F-Zero - 7.5/10
This game is a lot of fun. Kind of bland, but still fun. But it's also pretty hard, at least for me. I'll admit, I have stopped out of pure frustration. But, it's still one of those games where, despite the difficulty, you just have to keep playing...
Super Mario Bros. - 8.5/10
I'm not gonna lie; I never played SMB before this. It was before my time. And I just never got around to getting any of the remakes or ports. But, when I played it, it just didn't live up to the hype. Sure, it's great, but a slight letdown. Still, well worth $5.
Super Castlevania IV - 8/10
I'm not really too big on the occult. Well, I like Charmed, but that's about the extent of it. Nevertheless, when this game out on the VC, my friend urged me to get it. I wasn't disappointed. It's a lot of fun, seriously. Not one of my favorite platformers, but most certainly not one of my disliked.
The Legend of Zelda: A Link to the Past - 10/10
To the people who claim OoT is the best Zelda: break out your SNES and educate yourselves. OoT is a classic and is one of the best games of all time, but ALttP is just better. I'd never played it before I downloaded it, despite the GBA remake being easily available, but this is most certainly the best Zelda. My favorite Zelda? No, that's Minish Cap. But as far as quality, story, gameplay, music, and everything else goes, ALttP is by far the best.
Super Mario World - 9/10
Now this, this lived up to the hype. Granted, I didn't really hype myself up for this one prior to getting it, but it was still great. Riding Yoshi was a great element to the gameplay, and I loved seeing the Koopalings for once.
Gunstar Heroes - 8.5/10
I played Gunstar Super Heroes a while before getting this, and I loved it. But as good as that one was, the original was just better. Yes, it was hard at times (at least for me; if it wasn't for you, laugh at me all you want), but it was still a fantastic game. The hype surrounding this game is well deserved.
Star Fox 64 - 8.9/10
DO A BARREL ROLL! *cough* Erm, yeah... >_> This was my first Star Fox game, and reliving it on the VC is amazing. Everything looks better than ever, and the gameplay was just as I remembered. This is by far the best Star Fox game, if only they'd make more like these! I would've scored it a nine, but there's just one problem: no rumble. D:
Kid Icarus - 8.5/10
Considering all the good things I'd heard about this game, I went in expecting the best thing since sliced bread. Sadly, sliced bread is still the bigger bang. Kid Icarus is a wonderful game, and I enjoyed every second of it. Even though it is REALLY FRUSTRATING at times. It's my favorite NES game, even though I've technically only played 4, none of which on the original system (2 GBA, 2 VC).
