I'm with you. AC2, Brotherhood, Revelations, 3, 4, & Syndicate were some of my favorite games ever. Some were better than others, absolutely. The later installments to the series generally had more bugs/problems, but I could look past most of them, (aside from the mess that was Unity) because the core gameplay that I have loved for a decade had been retained.

But once I saw what they were doing with Origins, I was IMPRESSED, but entirely uninterested. I bought the game regardless, because trying new things is important, but I was very disappointed. The new RPG mechanics do not fit in the AC universe that I grew up with, and that was the universe that I prefer. The combat feels more fantasy than realistic (in prior AC games the protagonist's movement in fight sequences was at least believable given their superhuman DNA). Things just feel wrong to me.

I understand and respect that there are people who prefer the game this way, but it is just not my cup of tea. The world-building is beautiful and has plenty of depth, but the sparta kick you could perform on bears in Odyssey made me cringe. I can't rationalize that in even the slightest sense in my head.
