I played the first 2 NES games and all 3 OG Gameboy games in the early 90s. On a trip I had seen an actual TMNT1 arcade board and watched some footage but we had to leave and I didnt play. I was very impressed. It felt like the TV show, compared to the 8-bit graphics of the NES version and the lack of digital sfx.
Later tried the arcades and SNES port through emulation. TMNT3 on NES too. I read a lot in magazines about Tournament Fighters, but when I tried it in the late-90s I found it actually very crap.
Too bad that I had played SNK fighting games that were masterpieces compared to this.
Regarding atmosphere, favorite remains TMNT2: Back from the sewers and TMNT1:Fall of the foot clan for the Gameboy. Closer to the TV series though a bit too easy.
NES arcade port was better than the original in content with 2 extra stages and cool bosses (Tora and Shogun). Too bad they werent featured in the TV series. Same for the SNES version. Too bad that the arcade version played more fluid than the stiff NES and SNES ports.
TMNT1 on the NES I could finish it without problems. But I found it a chore.
TMNT3 on the OG Gameboy was one of the most tedious gaming experiences ever. I do not want to go through it again. I only finished it because we were travelling in Europe by car and it was the best way to kill time.
I personally like the art for the original comic, TMNT was an indie comic to begin with. The duo were more worried about the book selling well than it becoming a big media franchise.
The third Gameboy game was the first to catch on with the comic.
It featured a Triceraton as a boss. The Triceraton arc in the comic was one of the best. In the last fight the Turtles face 4 Triceratons and it is a battle to the death. What the 2003 TV series did to the arc was a disgrace.
