1. Mario Bros series, particularly 1, 3, and World - All amazing games that were completely new experiences for me at the time.
2. Goldeneye - Never played a game like it at the time, was blown away by the graphics and gameplay.
3. Mario RPG - Same sort of deal with Goldeneye, never really played an RPG before this, let alone an RPG in the Mario universe. Had so much fun playing through this game.
4. Secret of Mana - Epic RPG with amazing world, music, engrossing story, extremely fun multiplayer. Almost everything about it was perfection.
5. Everquest - First MMO I played and it delivered. I got countless hours of fun venturing and battling with friends. Some of my greatest times in gaming were in Everquest.
6. Starcraft - First RTS I played, and still my favorite to this day.
7. Oblivion - Completely epic RPG that surpassed my expectations.
8. Gears of War - Very fun and addictive game with great graphics, and one of the best TPS, with a great cover system. I still play it to this day.
9. Wii Sports - This is the game that game me that "fresh" feeling for games again that I hadn't truely felt since I first played Super Mario bros on NES. This was the game that sold me on motion controls.
