Buffy the Vampire Slayer fangame! The game interprets the opening of the worlds in the season 5 finale as creating a hodge-podge dimension of characters and locations from other works, resulting in a massive crossover world. Unfortunately, I am culturally illiterate and Buffy was the only one I was familiar with. The opening involves a hotshot demon hunter dude trying to protect her from demons only to get oneshotted while she beats them herself, which amused me and was delightfully in keeping with canon. Unfortunately, Buffy gets outclassed by everyone else pretty quickly. I can understand the necessity of flattening the power levels for an RPG cast, and it’s stated that the purgatory world is giving people additional magic powers, but it’s still rather annoying that Buffy isn’t that special gameplay-wise. At first I thought she was meant to have a unique weapon type that was superior in some way… except there’s another party member who can use more weapon types than her including her specialty weapon, and her specialty weapon kinda sucks anyway, having a lot of skills with random targeting and high health costs.
Despite that, I did find the Buffy characters to be very in-character, and Buffy has the same degree of proactiveness I liked about her from canon. Cordelia also shows up and is basically the best party member, which is awesome.
