Haven't had too much desire for newer games with live services, battle passes, etc. Got some that are still on my wishlist to find (physically) although I haven't really bothered much to search the retro game shops in a while.
Geist (Gamecube) - Interesting mechanics that I'd like to try out and I could swear I remember playing a demo on one of those Best Buy/Toys R Us video game demo stations.
Sega Touring Car Challenge (Sega Saturn) - Always enjoy the Sega arcade racers, so I'd like to see how their Touring Car game is after having so much fun with the likes of Sega Rally, Initial D arcade cabinets, and Outrun.
Mercedes-Benz World Racing (Xbox, PS2, Gamecube) - Not sure if it was physically sold in the US, but definitely curious to find it and play with it. I enjoy manufacturer based games that let you play with almost the entire lineup, even the dull and odd ones like in MB World Racing. Things like the C-Class wagon, Sportcoupe, E-Class wagon, etc. Edit: Wikipedia says they released in North America for just Xbox, so I still have some hope to find it.
GT Advance 2 Rally (Game Boy Advance) - Played through GT Advance 1 and 3, but never the rally focused 2. Of course, it's aged quite a bit, but I still find myself curious to try it.
Michelin Rally Masters: Race of Champions (PS1) - There were so many rally games back in the day, I just want to try them all out, especially when they have licensed cars. And my obsession of oddballs like it having the 1st gen Toyota RAV4.
Superstars V8 Next Challenge (PC, PS3, Xbox360) - Bought the prequel digitally on the PSN store, but would love to play with the slightly larger car list in this game. Love how different this racing series was, but sad it didn't last too long. Having doubts that they sold it physically in North America sadly.
Chivalry 2 (PC) - Really enjoyed playing the original with my brother in online bot matches, especially the hilarious voice acting. Hoping it's the same with this one and waiting for a Steam sale at a decent price. Maybe one of the few newer games I still would like to get.
Motortoon Grand Prix (PS1) - Curious to try Polyphony's first racing game, ever since Digital Foundry mentioned it, I really want to see the relations between it and Gran Turismo. Not sure if it sold in North America either.
I'm sure I have more to add, but didn't want to make the post too big. Thankfully have found most of what I've been looking for, for retro games. Just need to find time to actually play through them.
