Penguin adventure, litle pentaro does a triathlon.
I haven't seen him cycling though.
Run/Swim/Fly and once a while headbuting atroids....
10-YARD FIGHT, even though you may consider it more like an arcade game than a real simulator
What the MSX computers need (and still need) is a good conversion of Microprose Soccer
AFAIK the only barely decent football games available are Match Day, *MAYBE* Fighting soccer and Konami Football (that was probably the grandfather of Pro Evolution Soccer but none of them is a true masterpiece, like how Microprose Soccer was on the Commodore 64 back in the 80s
BMX Simulator!
I always like the Hypersports and Track & Field series.
/me more hours played = Football Manager
I really like the cartoon-esque matches!
