Most of my favorite games are already on all the “Top PS2 Games” lists, but my absolute favorite video game of all time is Steambot Chronicles, which got pretty much no attention at all. It’s really fun, with nice cell-shaded graphics and a bunch of stuff to do from piloting a big customizable robot to shooting pool to excavating fossils to decorating an apartment to playing a bunch of musical instruments with unique rhythm minigame mechanics! There are a bunch of dialogue options, too, affecting things from minor shifts in how your friends talk about you to a complete alignment shift to the enemy’s side, which obviously leads to a few different endings. Regardless of what ending you get you can still do the postgame content, though, so you don’t have to worry about getting any kind of “bad” ending. I’ve played it more times than I can count, and just keep coming back every year or two.
