Sometimes people say that Mario is also in the original NES Golf game (programmed by Iwata), but then sometimes NIntendo says, "Oh no, that was 'Ossan'" which is Japanese for middle aged man. The original NES Golf is one of the few NES games I could get my dad to play. I thought about getting him NES Open Tournament Golf for Father's Day when I was a kid, but he said he was perfectly happy with the original.
I played the N64 Mario Tennis game over at a friend's house. It was fun, but I never got it myself. I did review the Mario Tennis game on GBA, though. I loved Mario Golf: Toadstool Tour on GameCube and played it a ton. For some reason, I couldn't get into the 3DS version. I also have the Strikers games, they're a lot of fun. I'm glad Namco made the Mario Baseball games because they have lots of experience with their Family Stadium (Famista) series in Japan. The very first Famista game was brought over to the US as R.B.I. Baseball.
I had the first Mario & Sonic Olympic game and it was horrible so I didn't get any of the others. Did you know there is an arcade version of it? I actually liked Mario Sports Mix for its simplicity, and if you beat Story Mode in single player, you get to fight a giant Bahamut from Final Fantasy using sports skills in the other games! I also really liked the horse racing game in Mario Sports Superstars. Did you know Namco helped make that part, too? They also have a horse racing series in Japan called Family Jockey, so that's probably why.
I could never get into tennis games, though. Only one I really liked was SEGA Superstars Tennis (Ulala was in it). To me, most tennis video games are just glorified Pong games. So I'll probably skip out on Mario Tennis Aces.
