Starcraft. My middle school years were loaded with Starcraft and Warcraft 2. The sequels were great too! Honestly, Blizzard games have typically been solid and the majority of them have ended up in my top five games of the year for their respective years of release. I also liked Overwatch and Diablo a lot.
THPS has been a pretty good series, even if there have been some misses. I enjoyed Guitar Hero, even if the craze has passed. Spyro and Crash are both solid. CoD, for better or worse, has some of the most wonderful gameplay in history for the FPS genre, though the series has its flaws. Activision Blizzard has a decent amount of IPs.
