Those are just expansions/lazy remakes/quick cashgrabs.
Literally no brand new games. OP is correct.
remember when blizz was so mad at LoL for "taking their IP" that they tried heroes and even showcased the finals of it at blizzcon. it was so bad people didnt even play and it had all of the beloved characters instead of made up shitty anime girls.
im still chasing the high of co-op turret defense games from starcraft 1. they even had ones where the map revealed 1 square per round of a naked lady. boy those were the times.
