Gonna get a little retro in here.
- Crash Bandicoot: The Wrath of Cortex. It's effectively Crash Bandicoot 3.1 made by a different development studio. Pretty much just a rehash of the third game, except nowhere near as good and has absolutely no heart or soul.
- Spyro: Enter the Dragonfly. Exact same situation as Crash. "How can we innovate?" "Let's make him breath electricity and ice!". Well nope, that doesn't make for a good game when it's so poorly optimized; so badly designed and lacking so much content. A literal cash-in sequel.
- Twisted Metal 3 & 4. As soon as SingleTrac were pulled off the franchise it just went to shit. A "rolled off the production line" pair of sequels of the highest order.
To some extent, I feel like Ratchet & Clank: Size Matters and Jak: The Lost Frontier are soul-less sequels as well, but I did at least have more fun with them than the above games.
Basically: this happens often to ex-PlayStation franchises once the original developers do something else.
Tomb Raider in the 32Bit era.
That's a good shout. iirc, one of the developers literally said Chronicles was a phoned-in sequel:
"Tomb Raider 5 was effectively a load of old shit. That was the most depressing one for us. We were effectively just doing that for a paycheck because no other team wanted to take it on. So we had to do it, basically. By that time it had taken its toll. Three years of hammering it, and we were burnt out. That shows in the product."[
