It’s a pity OMF is so underrated. Whenever someone claims they’re a fan of fighting games, and I ask them which games they’ve played, not a single one of them has replied with “OMF” so far. :(
OMF also got me more into understanding PC networking. I made my own null modem cable once (by splicing up a spare RS232 cable), connected my friends PC to it and we played OMF against each other, on our own PCs! No more having to share our keyboard! (gosh, I nearly forgot that shared keyboard multiplayer was a thing…) Those were exciting times.
