WoW and Assassins Creed 2.

I burned them both in a campfire while ago :)

No. The important bit to realize is that Planescape's story IS it's gameplay with some poor combat parts strapped to it. It's like Dreamfall - I LOVED that game, you were running around, solving puzzles, talking to people and sometimes fighting and sneaking. While fighting and sneaking sucked, people did NOT judge it based solely on that.

In Planescape, you mostly run around, talk to people and sometimes solve a puzzle. The core of the gameplay is dialogue and decisionmaking. And then there is some combat. Clearly, there's something that just didn't tick with you, I'd say the setting - a lot of people can't stand it and don't even realize that. Nevertheless, Planescape's gameplay is awesome, it's all about dialogue and decisions - it's a shame there are those clunky combat bits.

I think some of the trouble may also be the slow start - I've bounced off it three times now. Nearly everyone says it only gets going after the first few hours....

One day I'll try again...

OK you said of ALL time right? - some of these are a 'little' old:

Tomb Raider - even though the latter sequal got REALLY bad the original wasn't great - the annoying thing about Lara is that she isn't a girl, she's a car, she has a goddam turning circle! What's THAT all about?

Defender of the Crown - success in the strategy parts relies to much on you being good at the arcadey parts

Sam and Max - now I LIKED Monkey Island but the puzzles in Sam & Max were just too obscure to live!

The Sentinal - I remember Zzap 64 gave this a gold medal and no actual percentage score because they said that it couldn't be compared to anything that had gone before - don't get much overrated than that, especially for a game designed to have a 2fps movement rate!

Renegade (C64 version) keyboard only controls for no apparent reason, Zzap 64 score in the 90s for no apparent reason

Great Giana Sisters - Super Mario rip off that Nintendo prevented from being released but only after mags had given it high scores so it became kind of legendary - I got a Yo Ho Ho copy and was most dissappointed!

There! Me = old!

Compared to most other RPGs (with the exception of BG2, which is a sequel though) I must say I find the start of PS:T pretty engaging, not as slow as the rest of them. :D

I've heard other people complaining about it, but never really understood that complaint. Must be a personal thing ...

Fallout 3.
I found the game design including the overall world, quests and dialogue to be bland to say the least.
Definitely not deserving the overall massive praise in my opinion.

Ooh - Pacman!
seriously - Pacman, it wasn't the first maze game or anything - in fact that year 'Rally X' was supposed to be Namco's big game, a car based maze game with 4 way scrolling, which was a big deal at the time, that's the one they spent the bucks (yen) making, they just bashed out PacMan as 'just another game' - I think Rally X is a better game!

I agree. The game just exudes blandness. The only thing that makes it worth mentioning is the atmosphere (which is pretty good) and the sheer scale. None of the minute-to-minute gameplay is good at all.

I think there's a warped, but ultimately consistent logic to this game. Once I got used to how the puzzles worked, I had an easier time with it than with many other old-school adventures.

Portal. It was okay, but nothing more. Even some flash games entertained me more than that. Definitely doesn't deserve all its praise and cult following. The same can be said about its song.

And basically any game that was massively marketed/advertised is overrated.

OH NO YOU DIDN'T >:(

Yeah? I must just have an incompatible mind then because I actually played through it because it WAS quite funny in places, but I swear I wasn't THAT close to the end when I even gave up only referring to gamefaqs when I got stuck and just played straight from walkthrough to screen!

And it's overall humour felt too forcing.
Like it constantly wanted you to know that it is so clever and randomly funny.
It just felt like a case of trying to hard.

Also, simple puzzles and short length.
That "the cake is a lie" reference still fucking annoys me.

Exactly.

I personally wouldn't say Portal was overrated. In fact, considering how much I enjoyed the game and didn't pick it up until Steam offered it free (so I was well aware of all the hype and had very low expectations), I'd say it's pretty darned good. The 'cake is a lie' meme is over used, for sure, but I don't think that makes it an overrated game. Personal opinion, of course.

Games I thought were overrated were Braid and Torchlight. I don't think I'd give them the 'most overrated of all time' award though, but those were two that got a lot of good word of mouth and I didn't enjoy them.
