That looks cool. Not what I'm looking for but interesting. Reminds me a bit of the MegamanEXE games.
Collectathons are just games (usually platformers) where you collect a bunch of stuff. Spyro you got the items in each level, gems, chests, sidequests (that give you items) and so on. There's a lot of stuff to collect. Banjo Kazooie is another collectathon.
