I buy a mix of both. And not all IPs have games that are similar. While games like Sid Meier's Civilization and Pokemon are approximately evolutions of older games, some franchises like Legend of Zelda and Mario have vastly different experiences depending on which games you play; in such cases, I often prefer a return to a familiar character; would I have cared about Sonic Adventure had it been Efran the Radioactive Rabbit Adventure? (or any kind of new character), I don't think so. That said, I get new IP titles all the time, and often prefer them as one-offs: Chrono Trigger is a great example, the idea of there ever being a sequel to that doesn't excite me; and I think even the brief links between Chrono Cross and Chrono Trigger hurt both games → some things should be independent.
So, I'm kind of in the middle on the question. Not really enough to commit to either side.
I describe myself as a little dose of toxic masculinity.
