3D Mario
Halo
Mass Effect

MLB The Show

I always get the main Final Fantasy games day one (including the original FF14 and A Realm Reborn... Guess which of those two i regretted ¬_¬) Same with Ratchet & Clank.

Other than that i tend to be pretty patient with waiting to get a game. I may still get something day one if it's being made by a developer i really like, or it's something i'm really hyped for, but nothing else get's an instant add to the day one list by name alone.

Hmm I really like Atlus's games but for some reason I rarely buy them day one. I only got SMT IV day one for the promotion. I can see myself buying P5 day one whenever that comes out.

Naughty Dog is probably one of my new favorite developers with this gen. I liked Jak, never played Crash which I probably should. I thought they really stepped it up with Uncharted. I'm ashamed to say I didn't get TLoU on day one and still don't have it yet. :(

Do you still consider Halo a high priority even with 343 handling the IP? I know people that fell out of that franchise after Bungie left. My roommate has never even touched Halo 4 even though he has every other game.

Smash Bros. is definitely something I'd put down full price for but the only time I ever got it day one was Brawl. And it was the one and only time I went to a midnight release. xD Still, even though I think it's worth every penny, it's not an absolute must for me. Maybe if the new one has a really awesome roster, I might just straight up buy a Wii U the same day it releases.

While I am late to the Halo series (started with Reach) I would say that one. Partially to avoid spoilers (the same reason I finished the last Potter Book before ComicCon.) But I really, really like/obsessed with IV. And I will confess I'm not a great shooter.

Another one would be Elder Scrolls VI! Though, the online version, I think I will skip. But whenever the next one comes out, as long as it still has Dragons, I will be standing in line, waiting to download it at Midnight!

Game series I've bought 1st Day and plan to in the future

Pokemon
Zelda
Super Smash Bros
Monster Hunter
Fire Emblem

I tend to pick up most other stuff at reduced prices although I'll pick up some other stuff new if it looks good and I'm not hurting for cash/games to play.

FIFA

Super Smash Bros, Mario Kart, Animal Crossing
