I love the first Lords of Shadow.
I will farm Schmoos for hours at a time to get a Crissaegrim. Sometimes two. Same goes for two Rings of Varda.
I prefer the accurate (though rather corny) translation of SotN's "Die Monster!" dialogue. I don't feel visibly guilty over this, but there's a lot of nostalgia points on the localization and I prefer the former. But then, fuck popular opinion, I like what I like.
Skeleton Leader is my favorite boss in the entire series. Period. Shitty gradient sword beam and all.
I torment the flirty enemies in PoR. For very long periods. Mostly the Henry VIII-looking guys.
Likewise, I also get a kick out of luring as many Succubi in a room as possible (in Aria and Dawn, mostly) into one crowd, so that Soma gets a harem, and then see how long I can evade the mob. This also applies to OoE with the Batgirls.
I quote The Undertaker whenever a Gravedigger shows up in OoE.
I read various lines of dialogue, from almost any game with it, in Robert Belgrade's voice. And it's majestic.
I still snicker like a twelve-year-old at Shaft's name. And all of his attacks. And proceed to make a "shafted" pun when I kill him.
I laugh my ass off every time I get to the cutscene in LoI where Walter's sitting in the throne. Stupid vampire, you're way too big for that thing, you look silly!
I constantly press the Up button whenever I'm playing as Charlotte. Guilty as charged.
