All of the Mass Effect 3 love in this thread.

1. Mass Effect 2 - Huge leap in combat quality from ME1, great character cast and mission premise (with loyalty missions) and still the defining end mission for a BioWare game.
2. Mass Effect 3 - Perfect character moments, the best TPS gameplay I've played, reintroduced customization elements lacking in ME2, important decisions, fantastic music.
3. Dragon Age: Inquisition: Superior action combat to 1 and 2, beautiful world, compelling and meaningful thematically, fantastic characters, dat Skyhold.
4. KotOR - A twist that defined videogame twists, HK-47, Bastila, light saber duels, best thing Star Wars since Empire Strikes Back
5. Dragon Age: Origins - Great cast, does everything else except combat well but nothing exceptional.
6. Baldur's Gate II - This would be a lot higher if I didn't have a distaste for point and click gameplay and Vancian casting. The writing, world structure, and RPG elements are top notch.
7. Dragon Age 2 - Had this not been rushed it would have been way higher. Unfortunately it was rushed, and this caused several significant issues in the game.
8. Mass Effect - Bad combat, clunky RPG mechanics, empty worlds (emptier even than DA: I's) and underdeveloped characters. Great plot and world building.
9. Jade Empire - The worst combat BioWare has done. Not many interesting locations. Good sidequests but character dialogues are rushed to compensate for its short length.
10. Baldur's Gate - Doesn't have the good writing of BG2, several other elements undercooked.
