Shadow the Hedgehog. It's a decent game with loads of replayability and one heck of a secret final level if you're a psycho like me and played every single combination of mission.

A snoot boop is a snoot boop I'm gonna boop the snoot

Ah yes! Seeing if you can interact with the animals!

Step in the fire

See if I can swim

Mandatory

Depends on the context.

Generally Good

If they're for things that don't impact multiplayer experience such as cosmetics with no stat boosts

Exp boosts for single player games

Generally Bad

Items that give players an edge in multiplayer (stat boosting cosmetics, weapons, etc)

Limited time items that force you to either grind battle passes or flat out purchase through premium methods

Just a few examples.
