Sports games I have played and enjoyed over the years...
10 Yard Fight (NES)
Super Techmo Bowl (NES)
Super Dodgeball (NES)
Nintendo World Cup (Gameboy)
Madden 92 (Genesis)
NHL 94 (Genesis)
Road Rash 1 & 2 (Genesis) - Hey, it's racing. =p
Mutant League Football & Hockey (Genesis)
Mario Kart (SNES)
F-Zero (SNES)
Diddy Kong Racing (N64)
Gran Turismo (PS1)

Tony Hawk...2? (Whichever was the first PS2 installment).
Wii Sports
Rocket League (PS4)

...and that, as they say, is that. Not my least favorite genre, but it ranks fairly low on my interest radar.

Edit: Forgot Hot Shots Golf (PS1), WWF Raw (PS1), and WCW/NWO Revenge (N64).

Mario Strikers. I love that game so much.

Where is the Soccer with Cars categoy?

I'm more biased for combat sport games. I mean, what's not good about two guys in tight pants grappling each other into submission?

It use to be racing games, but past 5 years or so have been wasteland for the genre for me. Gone are days of fun couch co-op racing a friend. Pretty much only racing game had fun with in recent memory is Mario Kart 8.

Given that Football via FIFA has become best sport/party game to have a fun evening with some friends. Playing 1v1 or 4 people v CPU is a blast even if you're playing an iteration that is a few years old.

Also, I agree about skate games. I love THPS 1-4, but after that have not enjoyed a skating game. Same with SSX after Tricky.

I've always liked boxing (fight night) it's great for offline pvp aswell.

Hmm, I really enjoyed the Mario Tennis and Golf games. Also Megaman Soccer. That was fun...

Hockey games then racing probably.

I wouldn't include Racing or Combat sports in the poll. That being said, I love a good sim racer.

I liked Tony Hawk series up until 2007.
and Mario Gold Toadstool Tour was always a killer game
