---------------
For Samurai Shodown, I considered it "beat" since that was the day I finished the story mode with all characters, unlocked everything, and obtained every achievement. Fantastic game but the load times are brutal, even on a Series X. Load times on regular Xbox One were to the point I couldn't even stand to play it. Save scummed my way through Genesis Tournament Fighters on hardest difficulty to fight the final boss and get that achievement on the Cowabunga Collection... horrible game, as bad or worse than some pre-SFII fighters.
Went through Guitar Hero 3 on easy career since the achievements don't stack for harder difficulties. Played through Castlevania on the Anniversary Collection. Thank goodness for save states, as I would have never made it otherwise. I never owned this one back in the day and the farthest I think I had made it before was the Frankenstein boss.
