I haven't encountered that but most of the time you're running through narrow corridors anyway.

For me, corridors are okay, because that makes sense - you can't walk through a wall, so you can't progress that way. On the other hand, wandering around an open-looking environment only to have "YOU ARE LEAVING THE COMBAT ZONE" pop up at some arbitrary point is a huge affront to me.

I didn't mean literal corridors, even if there are some of them.
What I was trying to say was, most of the time something (walls, debris, mountains, trees, invisible walls) is blocking the way on both sides, like a corridor.
For example: There are two trees and it looks like you could walk between them but an invisible wall blocks your path. Or if there is a small cliff and you want to drop down to use a shortcut, most of the time it's impossible because the invisible walls won't let you pass.

Finished:

Potato man and the Search for the Troof - a surreal, trippy and amusing game, but very short indeed, although it does have its fair share of tough moments. The ending is practically non-existent too. I liked the game but my god I'm glad I didn't pay much for it (got it in some bundle or other).

Totally Tiny Arcade - completed on my first go and never want to play again. Not because it was bad but because it just dragged on and on and wasn't even difficult. A nice bit of nostalgia I'll admit, but only when you recongise the games it's mimicking.

Dishonoured - loved it.

In the past month and a half I finished the following,

Warlords Battlecry 1 - Decent enough, but it was kind of buggy. The sequels are way better.

Colonization - Finally beat this game on Conquistador with the Dutch. It took a lot of restarts to learn this game, but it's pretty amazing. Definitely gonna go back to it again some time.

And I just beat Eschalon: Book 1 - Pretty fun and at times difficult game. I went with a wizard/unarmed combat/stealth build that worked pretty well.

The rest of my list is here

Finished Colonization. I had to restart a few times before I get the grasp of the game (although I played a loooong time ago when it was released). I had chosen easy difficulty and the English. Final score: 26%. Now that I beat the game, I could do better but I have other games to play.

So far this year:
- Alone in the Dark 3
- Amnesia Fortnight Prototypes
- Blackwell Convergence
- Blackwell Unbound
- Brutal Legend
- Cognition Episode 1
- Colonization
- Deadlight
- DLC Quest + Live Freemium or Die
- Host Master and the Conquest of Humor
- Host Master Deux: Quest for Identity
- I Am Alive
- Karateka
- Law & Order Legacies
- Lucy & Lola's Big Adventure
- Nelly Cootalot
- Offspring Fling
- Red Faction: Guerilla
- Splinter Cell: Conviction
- Syndicate
- The Blackwell Legacy
- The Cave
- The Darkness II
- The Experiment (Experience 112)
- The Walking Dead: 400 Days

Just finished Mario & Luigi: Partners in Time on my 3DS (although it's a DS game), in around 19h. Last time I gave up at the final boss, but this time I managed to beat it fair and square!

That's a very nice game, and that was 19h without any boring moments! I hope the next installment (Inside Bowser Story, if I'm not mistaken) will be as fun as this one. I should know soon, because that's what I'm going to start to play tomorrow in the subway... ^_^

So far in 2013: http://www.gog.com/forum/general/games_finished_in_2013/post31

IMO, Bowser's inside Story is many times better than Partners In Time.

I remember having tried it on the DS of a friend, seemed very good indeed. Seemed much longer, too.

Just finished Thomas Was Alone.
Elevated to brilliance by the absolutely fantastic narration. I laughed and laughed, and felt sad, and happy, and laughed some more. Nice soundtrack too.

Dwarf Quest i must say that is the shortest game i've ever played.

Just finished it as well; I felt the same way. Although, some of the gameplay was not great; a bunch of glitches (getting stuck on walls, for example), some very repetitive sections, hard to tell which character you're switching to - particularly in the later levels.

Anyway, I still really enjoyed it - I really loved the narration and the music.

Finished tonight Bioshock: Infinite (PC).

Added it to my list of finished games in 2013:
