What games were the first that you either got with or bought for your systems when you first got them? You don't have to post all your systems if you don't want to, atleast your newer/latest ones that you play.
Mine:
NES- Super Mario Bros, lol of course
Genesis- Sonic, another no brainer at the time
SNES- Super Mario World, I remember my dad buying the system and it coming with it.
Gamegear- Shinobi
N64- can't really remember. I rented a lot then, but I think it was Banjo Kazooie. ???
PS1- Tekken 3, I remember playing the first 2 on my bro's ps1, and when I finally got one, this just came out and I was sold.
PS2- NBA Street, awesome awesome game. 
lol
Gamecube- Gauntlet Dark Legacy
GBA- Mega Man Zero, best family trip ever, cuz I played this the whole time.
Xbox- Halo, loved it when we rented it for my bro's Xbox, so when I bought mine I had to get it.
Xbox 360- Gears of War, loved the look, played it at a buddies house and it pretty much sold the 360 for me. Although I was kinda out of it after the 2nd and not really looking forward to the 3rd, lol.
Wii- Twilight Princess, gots to have my Zelda. and since this was a launch title, it was inevitable.
PS3- MGS4, bought the bundle online.
PSP- FFVII Crisis Core, one of the reasons I bought it for.
Thats all I can think of and pretty much think most of those games are my first for each one. Just not sure on the 64, I think it was Banjo, but still not sure.
Mega Drive - Sonic 1
Saturn - Sonic Jam
Dreamcast - Sonic Adventure
Playstation - Tomb Raider and Formula 1
GBA - Sonic Advance and Tekken Advance
Playstation 2 - Gran Turismo 3
Gamecube - Sonic Adventure 2 Battle
Xbox - MGS2: Substance, Halo, DOA3, Shenmue 2
DS Lite - Sonic Rush
PSP - Little Big Planet, Soul Calibur Broken Destiny
Xbox 360 - What I was doing was buying games before I had the console... So I cant really remember. Sonic The Hedgehog was there though. 
Genesis - Sonic, you were expecting something else?
PS1 - Final Fantasy 7, the game that got me into gaming, I still remember being 10 and beating Ruby Weapon
Dreamcast - Sonic Adventure, the game that made me a Sonic fan
PS2 - Final Fantasy 10, what I consider the last "must have" game of the franchise
DS - Super Mario 64, one of the best games on the DS
Xbox 360 - Gears of War, only played the first one but boy was it fun
PSP - Crisis Core, the best of the FF7 spin-offs (that's not saying much)
Wii - Twilight Princess, Zelda is always a must have
Gameboy Colour - Pokemon Yellow. I was impressionable 🙁 Didn't like it too much but played it cause it was SO COOL. Also first game I ever bought!
Gamecube - Super Smash Brothers, SA2:B.
DS Lite - Warioware touched
Xbox 360 - Assassins Creed, which is one of my favourite ever games. I like stabbing people 😀
and since i'm somewhat console deprived compared to you lot:
PC - Tomb Raider AoD. It wasn't very good compared to the other Tomb Raiders I've played. Also this is just the first game I bought myself for PC since it was my Dad's system 😀 I haven't actually bought myself anything for my own lappy I bought myself november last year since I've been focusing on other things like wasting time sitting on forums. Got AC2 for my birthday though, EXCELLENT.

This might get long. Let's see, in order of console age (and not in order I bought 'em)...
Master System: After Burner, Phantasy Star and Rastan came with it.
Game Gear: I got two or three games with this, one of which was a multi-game cart with Columns. I think? I also got Sonic Chaos and Sonic 2. I think.
Mega Drive: I think the first game we got for this was Mortal Kombat II, not 100% certain.
Mega CD: Sonic CD. Bought it at the same time.
Saturn: The first thing we actually had for this was a Demo Disc that was on the cover of a magazine. The first actual game we got... I can't remember now.
Dreamcast: Sonic Adventure. The entire reason I bought the system. ^^
GBA: Sonic Advance.
GameCube: Legend of Zelda: The Wind Waker Collector's Edition i.e. the one that had OoT Master Quest packed in with it. This was packed in with the system, which was a Platinum Cube.
DS: TETRIS!
Wii: Wii Sports (obviously), bought LoZ: Twilight Princess at the same time. Like just about everyone else XD
Oh and I also bought a PC somewhere along that timeline, just before my Cube I think. First game I ever actually bought for that was Descent 3, I think.
For the Genesis, it was Sonic 2. Ironically, for the Game Gear, it was also Sonic 2.
When I got the Dreamcast, I had 3, which were Sonic Adventure, PSO Ver. 1, and Power Stone (whoop!)
Then, when I got my Xbox 360, my first game was Skate. Which I still play. Far too much.
