So I have a lot of these and I'm not sure if anyone can help me find some of them but I played most of these in the early 2000s so theres a chance they came out in the 90s
I remember playing this game where there was just a black screen but you could place things on the screen with the mouse, like people, buildings, giant worms (I think) then there were an assortment of weapons like a flamethrower, bazooka and gun, but the gun was blue and shot ice, there was also a version of the game where the gun was just a regular gun and not blue, but I only played the Ice gun one, I'm pretty sure it was called Ice Gun but I can't find it anywhere
secondly, there was a game where you played as this red guy and you had to bounce around like you were on a pogo stick to get over obsticles, but if you hit your head too hard your red hat would turn white and you'd die and have to restart
thirdly, there was a game I played on the snes I think, where you played as these mech suits in a semi 3d environment, it was kind of like star fox but you were on the ground I don't really remember much from the game apart from walking around this green emptiness and occasionally finding a small hill, but I think thats cuz I walked away from the area the mission took place in
There were also 2 lego games, one where you got the view of an area and you got to build your own cities and stuff, I remember there were occasionally skeletons walking around the forests and if you clicked on them they'd fall over and turn into a pile of bones, the second one was a Harry Potter lego game where you played as Harry and walked around and built Harry Potter lego sets or something, I didn't know the controls to I just walked around, I'm not even entirely sure if it was Harry Potter related but thats what I remember :/
