I don't use a widescreen monitor.

Even if I did, I would generally prefer to play games in the original resolution, as black bars on the sides don't bother me at all; on the other hand, a stretched or poorly scaled image does.

It's also worth noting that I don't like general bug fix mods; I prefer mods that either do one thing or can be configured to only fix the specific bugs I want to be fixed and not those I don't (in particular, I don't like it when mods force "fixes" for exploits and certain cases of unusual behavior, but I might want fixes for critical bugs (like, for example, crashes or softlocks likely to occur while playing casually) and abilities not working at all).

The Morrowind Code Patch is nice because it lets you pick and choose which fixes you want (but I don't like some of the default selections).

The Baldur's Gate 2 fixpack is not nice because I can't just choose to have critical bugs fixed and not break the stacking of certain effects (Armor of Faith comes to mind).

Some widescreen fixes improve the gaming experience because they can get rid of the black bars on the side of the screen, but sometimes it also does so at the cost of some minor / major inconveniences.

A good example of that is the Commandos series :

- In the 1st game, it is really helpful because the screen can be divided into several independent sections covering different zones. So, having a wider screen helps since it gives you more comfort regarding that aspect. BUT, this widescreen fix also has a minor annoyance : it seems that with it, the game's framerate has been lowered a bit. Nothing terrible, hopefully. Still, it should be noted.

- In the 3rd game, there is a fix, but it has the major inconvenience to make the game unstable, especially when making the game's resolution greater than 1280*800. Under that, crashes are not too frequent, but over it, it becomes nearly unplayable.

Widescreen makes sense - our eyes aren't vertically aligned. Games that were made with widescreen in mind usually have a user interface adapted to that. Games that weren't... you can still play them in their original aspect ratio.

Differs from game to game. Quite a few older games' HUDs consist of separate elements that are aligned to the screen borders (and center) and will work as intended when using a widescreen resolution.

Your eyes focus on the same point unless you look like this. :p

Irrelevant.
We're talking about eyes here, not periscopes. Did you think that FOV was just some "game setting"?

The man in the picture is not periscope and does not adjust his FOV with game setting in his head.

Widescreen for movies when needed, normal ratio for everything else.

Don't get me started on triple monitors.
You are not knight in fancy helmet or eskimo.

ps. Though I would admit there are some games that would suit it. Like a FPS knight game or on a narrow bridge of a vessel but then you would want a 4th monitor at the bottom to look at controls or even a 5th above it for roof switches if it was something like an airliner.

To be honest I also have been told that widescreen is more adjusted to the natural way our eyesight is working. However it seems I was (like many others) wrong:

Anyways - I still prefer widescreen in both PC and movies but maybe that'S just a subjective thing.

I just like wide screen since I can push the UI off to the sides.
