I can't pin down one favorite, so I'll go with several.
New Vegas: Constant audio stuttering, oddly moving models, and slows down/possibly breaks when you look at it funny. Also, for such a touted feature, it just throws the whole companion thing at you (and they're not that smart; ED-E got knocked out several times on me shortly after getting him. No way I'm playing hardcore mode).
Half Life 2: Constantly grabbing things with your gravity gun and using them as platforms isn't an interesting challenge. Thank god you let us control the antlions later.
Super Mario World: I know the special stages unlocked in the Star Road are supposed to be exceptionally hard, but Tubular is just hell.
Thousand Year Door: Keeping track of 100 small creatures while walking around a tree dungeon does not a fun puzzle make.
Tales of Symphonia: Look, my jaw dropped when I first reached the Tower of Salvation. I loved how it utterly deconstructed the whole "chosen one saves dying world" plot. However, why did it start sliding in the second disk, resulting in a pretty straight cliche finale? Also, it could have done more with the Desians, I was feeling pretty awesome going around raiding camps, feeling like the leader of the Inglorious Basterds.
Metal Gear Solid 3: Knocking out Raikov and dragging his body to the locker room is pretty much impossible without just killing all the guards, and considering that it's a Metal Gear game, that's not a viable option. Thankfully you can just wait for him to get to the empty locker room and knock him out there.
Phoenix Wright (series): I understand that your challenge comes from making obscure deductions in presenting evidence, but many pieces of testimony pretty much require you to follow GameFAQ's directions much of the way through. Also, Moe the Clown can burn in hell (and his case, for that matter).
Fire Emblem 7: Please allow the option to both save mid-level and start from the beginning. Removing permadeath would be stupid, yes, but at least don't make me start all the way over because I left Lyn just within Wyvern reach or got insta-zapped by someone in the fog. You provide one of the best strategic experiences I've seen (partly because of your greater focus on characters, instead of the "create a soldier" shit in so many other SRPG's), don't weigh it down by making difficulty directly equal frustration.
Persona 3: Don't make me choose between good presentation (FES) and the ability to control my allies (P3P).
Metroid Prime: Remove Fission Metroids, then I might have beaten you.
