Commenting on what I flubbed, but I did decently this go around. Followed the same scoring method..
ROUND 1 - 11.5 points 0.5 for picking MGS4 instead of MGS3, did not guess Blue Dragon, did not guess Monkey Ball (presumed it was a Katamari)
ROUND 2 - 25.5 points total (got all the triple themes correct!) Group 1: 6 points - Group 2: 5 points (did not know the third game, but guessed theme via context) Group 3: 5.5 points (Lucked out on TMNT:Shredder's Revenge from playing Arcade a lot as a kid, guessed Mario Party 1 instead, got the theme.) Group 4: 4 points (guessed the wrong Sonic, guessed Duodecim, picked up Final Fantasy half-pointer, and I really should've known Kirby after VGMC16.) Group 5: 5 points (Still haven't played Omori and didn't guess it, did not make the "duh, it's Chaos" connection.)
BONUS ROUND 1: 2 points (for the third one, guessed Atelier Iris, should've guessed Ar Tonelico because of our weekly Kama quizzes on VGMQ, and strangely, only one I got was Live a Live which is on my to-do list.)
ROUND 3: 26 points (Nearly perfect except I was dumb and for SMB3 I guessed Boom Boom instead of the Hammer Bros.)
ROUND 4: 18 points Did not get Dreamcast, PSP, Steam Deck, or Phillips cd-I
ROUND 5: 17 points (-1'd for wrong Mega Man series, but +3 for title screen for a net +2 for #2, even 0 for Advance Wars because I guessed Sami instead of Andi. Also, the post-commentary on Castlevania kills the Isquen.)
BONUS ROUND 2: 0 points No spoilers here other than I didn't get any of them :D
