I remember when my nephew first asked if I knew about Roblox. I was so excited to build some stuff with him, until he showed me this crappy superhero fighting simulator. I can’t complain too much, since it’s basically the new-age version of crappy flash games, but it was still a disappointment.
I found it back in the mid-2000’s while I was looking for a video game where I could build stuff, similar to legos, so when I played it all I did was make castles and robots and whatever. Maybe you could make minigames for people like they do now, but it didn’t seem like it was the main focus, at least from what I had seen back then.
