I can never pick a favorite game, but I can tell you which games I enjoyed the most last gen.
Bayonetta is a great action game, with excellent and fun gameplay. I also enjoyed the music a lot, specially the angel and major battle themes.
Demon/Dark Souls. I bought Demon Souls on a whim. I had heard that it was a pretty good game, so I bought it without even watching gameplay videos. I was hooked instantly.
Dragon's Dogma. it's an action RPG with really good gameplay. Think Devil May Cry combined with WRPGs like Oblivion. The graphics are pretty average, and world map isn't as big and doesn't have much variety (only one city, and two small towns), but the gameplay definitely makes up for it. I got almost 200 in just one playthrough.
