Yeah, of course i remember FPSFree!
Back then i was a kid who discovered FpsC by accident, just searching "how to make a game". I've tried TGF2 already, and made little project in Rpg maker, and then I discovered FpsC
When i first read about it, I thought that it's some kind of scam, cuz its description sounded literally too good to be real ;p But I've tried it anyway
To my amazement it had real 3d graphics, and i could just drag and drop enemies and shoot them minute later - for me that was more than enough
Back then (i think it was around 2008-09) there was little polish forum about FpsC (now dead for looong time) and - since polish was my only language back then - I could learn some basics. Everybody on that forum were trying to make a horror game, so - to be original - i was making action shooter... 7 levels of killing nazis without changing even one script
Of coure laggy as hell
Let's say slow-motion was a feature
Oh boy if i only had backups of my first "games" in fpsC it would be fun
Or maybe not... ;p
Ok but that is too much off topic ;p
