I mean… if you were to buy a Tomb Raider video game, you’d likely have a good idea at this point what to expect. I don’t see why that would be significantly different for an RPG.
Possibly. If I buy a Star Wars game, I might not. The sorts of games to which IPs are attached can vary in style and content. That's why I think this discussion would profit from ditching discussion of Tomb Raider or Lara Croft.
I really don't get this Tomb Raider discussion. At all. And to be clear, I am addressing this to basically everyone involved.
It doesn't really feel like what people are actually talking about when discussing "themed games" vs. "generic games." The fact that it involves an IP does not clarify anything. It further muddies the water. For example, people talk about using 5e D&D for everything and treating it as if it was a generic system. Wasn't there a Stargate game that used the 5e system? Is that a themed game or just a themed supplement of a "generic" game? So all this Tomb Raider stuff is such a weird rabbit hole discussion. It's treating IP-based games as if they represented the lion's share of themed games.
If we were talking Monsterhearts vs. GURPS/SWADE for telling stories about sexy monsters, teenage angst, hormones, high school drama, and LBGTQ+ themes, then I would understand this discussion better. It would be a discussion about a specialized game vs. generic game (plus supplement and/or kitbashing).
If we are wanting to talk about themed games vs. generic games, then I think that it would be easier if we dump the IPs from discussion. IPs can be associated with "themed games" but also games that stylize themselves as more generic games. Old Gods of Appalachia and Magnus Archives are "themed," in terms of the aesthetics of their IP but they both build on the fairly generic Cypher System, and it's questionable the extent to which the system actually enhances the gameplay playing stories for these IPs. We talked earlier of games mismatched to systems - e.g., 5e D&D, PbtA, FitD, etc. - and the same holds true here.
IMHO, we all need to take a step back and ask ourselves:
What is this conversation really about at this point? What are we actually discussing here? Have we lost the plot of the discussion? Are we better served by dropping this Tomb Raider talk in favor of finding the plot?
