The "light and fun" part comes from the fact that Edna is a very innocent character, so her childish actions and her comments are often quite funny. But yeah, there are good reasons she's been locked up in there.

I would like to play Close Combat (the first of the series) again, but I cant its a windows 95 game.

Any game with motion blur that I cannot turn off or games that continually and jerkerly changes the perspective.

I cannot play Deus Ex 3 because of this. If I could force the game into 3rd or 1st person mode I could cope better, but as it was, the first section where I tried sneaking I got motion sickness and that was that.
Motion blur also gives me motion sickness, so when I play GTA's, Saints Row or any racing games I have to turn that off too.

This reminds me of a lot of the NFS games where you can't turn off the 'glow' or 'glare' or whatever the hell it's called. It drives me nuts and I need a pair of sunglasses just to play the damn thing.

The way you phrased that question ("So you never play games that can be fun for 20 hours or so?") sounds a bit condescening, and I don’t like that. But never mind.

20 hours play time for Planescape Torment surprised me, so I asked Google, and 20 hours seem to be more realistic if you rush through the game, knowing where everything is and having read the dialogue before, like you surely did, having played it several times. Some write that 40 to 50 hours are more realistic if you read all the dialogue, explore every corner and take your time. I started the game once, several years ago, and spent almost 2 hours in the first area alone, before I got distracted by other stuff and stopped playing the game. Still, 40 hours play time is less than I actually assumed, so I’ll probably give it another try one time.

But there is one other thing that keeps me from playing the game, and you already mentioned it. There are so many different ways to play through the game, and since I probably will play through it only once, I will try to get as much from this one playthrough as possible. To achieve this, I will probably need a game guide, but using a guide takes away a lot of fun and spoilers things. So this another thing that kind of paralyzes me when I think of playing the game – not knowing exactly how to best approach it.

Looking on Google, it appears there is a segmented speedrun that beat Planescape: Torment in under 21 minutes. Of course, this would not be a realistic time for someone playing the first time, as the player is likely intimately familiar with the game, plus there are glitches used that likely allow the player to skip large portions of the game as well as cutscene breaking.

Then again, the expansion to Baldur's Gate 2 can be beaten in around 8 minutes.

I think there is a missunderstanding here. I don’t want to speedrun the game. I want to play through it properly, exploring everything I can and taking as much time as I need.

I was just giving that time for point of comparison. Also, getting both familiar with the game and good enough to actually beat the game that quickly will likely take a lot longer than a single thorough playthrough. Speedruns are not for first-time players, so feel free to take your time and explore the game.

It is, however, sometimes interesting to watch speedruns to see what sort of tricks people can come up with that the developers (usually) didn't intend.

I don't understand this, if it is fun to play multiple times, then why not do it?

Again, why this condescending undertone? Just let me play my games the way I want to play them. And for story-heavy games that is usually only once, because once I know the story it’s usually less fun and interesting the second time around. At least, that is how it works for me. I hope this answer is to your satisfaction.

The condescending tone is fully intentional. These games were meant for 13 year olds and here you are thinking about whether or not you "can" play them for hours instead of just doing it.

In this case, the same that applies to how I play may games also applies to how I spend my time: the way I want to. End of transmission ;-)

There is no need for truisms,but here is another one: if you bitch about the way you spend your time here you need to be ready for comments about it.

Nvm... I got lost in translation.
