STAGE SELECT:
Not really a "guest appearance," since these characters don't physically show up in the game, but the PS5 Ratchet and Clank has a side quest involving a lombax that tries to map every dimension in the game's universe and some dimensions are clear references to Sly Cooper, Knack, etc. The way it was done is such a neat little Easter egg and it's fresh on my mind, so I thought to include it.
Link in Soul Calibur II got me to play Soul Calibur, so I'd honestly say that's the most recognizable "guest spot" in a video game to my memory/for me personally.
I couldn't think of anything else off the top of my head, so in honor of your previous episode I went looking for Street Shark cameos and found out there is an Easter egg reference to them in Tiny Tina's Wonderlands.
There were unfortunately no Google results for Guilty Gear characters showing up in other games, to my immense disappointment.
VIDEO GAME CAGE MATCH:
I had way more fun playing Driver 2. I've always loved driving in video games and I honestly think that game may have started that for me.
Syphon Filter just confused me and I think that had a lot to do with how young I was at the time. I don't think I ever made it very far and to this day I die pretty easily in most shooters. Less so in third person ones like SP but moreso than most other genres of game.
