I have a few games from my childhood that I can vaguely remember, but I've tried searching for them and couldn't get anything.
I think they're all PS1 games, not sure as my dad had set up an emulator, so I wasn't physically booting up a console that I could remember.
The first game, I believe the main character is some small dude in a yellow/orange suit, running around on a beach or an island, doing platforming and stuff. Don't really remember much more. :(
The second game, it was sort of like a medieval setting, it had a dragon I think and I believe it was themed after some toys. Not Lego, something else, the characters all had straight arms I think. The player character was a knight, might've had some blue-ish armor.
The third game, actually I think this was a demo of a PC game. It was set inside some kind of a mine, the main character was some red devil-ish? looking dude who had a brown staff I think. Again, not much to go on.
The last game, this one's been the biggest mind breaker for me - it was a racing game, I'm 90% certain it was some kind of sci-fi bikes, going at huge speeds on these tracks that were like.. floating? It wasn't like racing in the streets, more like futuristic roads set in a pretty gray world. I think there were some huge towers that the tracks would go inbetween/around and such. This is by far one of the earliest games I've played and thus is the hardest to recall.
e: another one came to mind, also very vague, this was from a game magazine demo disc on PC. It was set in some small town, you played as a guy in a suit, I believe, possibly an adventure/detective game. The most distinctive thing I recall about it is that you could whistle a cab to travel to different places.
