Have you ever started to feel a game you once really enjoyed really wasn't as great as you use to think it was.
Lately I've really felt that way toward Assassin's Creed and the Arkham games.
With Arkham the games always tell you where to go, constantly drop hints and prompt you and cluster the hud with info. The enemy ai is really stupid in the stealth sections and the combat usually consists of hitting the attack button till you're prompted to counter with the exception of a few enemies that require you to stun or jump behind.
As for Assassin's Creed a lot of the side activities and the stealth system itself feel inconsequential. I'm in the minority here but I actually thought the first one was pretty good because stealth had a purpose. The combat is horrendous and like Batman you're constantly babied, given button prompts and constantly shown where to go and what exactly to do and how to do it.
Same for 3d Sonic though, rather Sonic Adventure 2. The cutscenes, voice acting and music are so harshly cringe inducing, the camera is frustrating, only the Sonic and Shadow levels are any fun
