Lemme explain what ACTUAL retroslop is.
It’s a term used to describe games that try to appear retro by overusing studs, but they fail horribly. Games like grow a garden and weird strict dad are good examples of it. They also don’t put a lot of effort into the game (hence where the slop part comes in).
Games like forsaken, regretevator or SEWH may have retro characters, but the game itself has nothing to do with it. For block tales tho, it’s a time travel game. It takes place in 2010, so it’s obviously going to be retro.
For avatars, stuff like this would be considered retroslop because it is overusing studs. The other stuff you’re seeing? Mostly cosplays (mainly Regretevator or forsaken, which again, only have classic characters but have nothing to do with being retro.)
