yeah that has to be a pac-man game ever if i ever played one

I feel like this has to be the most "safe" Pac-Man game I've ever played. It's fair enough but it barely innovates outside of adding power-ups and that bonus fruit mazes (which are very difficult). The graphics are passable for it's time but it does sort of feel disappointing especially after something like Pac-Man Adventures in Time, which only came out a year after that. The sound is pretty empty-sounding for a Pac-Man game too; even though I found the music repetitive, I sorta did find it chill at the same time as well.
Aside from those, it really just feels like it fails to innovate past the regular Pac-Man formula as the stages become incredibly repetitive with no unique mechanics and twists. Dunno if I could recommend this one at all.

Championship Edition 2 builds up pretty well as a Pac-Man maze game, although I found it the difficulty for this game in general to be a bit harder than I initially expected, which is why I prefer CE DX and the original CE over 2.

The Adventure mode was especially hell, considering the difficulty it requires and absurd unlock requirements for other things. The strict difficulty, the game not telling you that every level needs to be finished on the hardest difficulty in order to finish the mode, the immersive difficulty spike after area 6 are what just makes the Adventure mode frustrating to me honestly. I prefer playing the regular Score Attack mode over Adventure personally.

Despite the flaws, the visuals and music are gorgeous and some of the best Pac-Man's ever had.

Sonic Adventure 2 Battle (along with Sonic Advance) was one of my earliest exposures to Sonic as a whole around 2007-08, though they weren't the things that really got me into Sonic, I decided to give the game a play after these years. I initially began play with the original Dreamcast version, but restarted with Sonic Adventure 2 Battle midway through the Hero story.

Some of my issues from the first Adventure game persist in this game along with some new ones, specifically the camera, clipping (especially during Sonic/Shadow levels), some controls, the pacing (to be specific, the changing play styles between levels), and voice acting for some characters. Some bosses and specific level sections were super difficult to get through, most especially the Finalhazard boss (that boss alone cost me 20+ lives).
Despite those, I really enjoyed the play styles altogether, alongside the amazing music, level design, Chao Gardens, secrets and the story. Of all the play styles in the game my favorites were Sonic/Shadow's stages.

Overall neat experience, though there are a few points where I'd prefer the first Sonic Adventure over 2.
