I founded something yesterday : ZDOOM.

It requieres the original doom game(s) to work, its something like an adapter and some more, makes doom running cleanly in the computers of our days, mouse support, no shity enchancements such as remoddeled things as it can be found in JDOOM (in JDOOM the models of the mosnters and weapons are changed for example, and it more have the look of crap than somthngi better).

ZDOOM adds the possibility to jump and crouch, and the most interesting : the up and down mouse look, and it adds a crosshair that is handy with tridimentionnal mouse mooving, there are some other features, but its possible to play the game with all the basic features as the game originally was.

This adapter can be used only to ensure compatibility with nowaday OS for the purists, or to add some neat features.

The DOOM 95 demo is stil available to download here for example : http://www.download.com/Doom-95-demo/3000-7453_4-855497.html

And the games are still not free (meh) and for sell for like 20$ in the ID software site.

These days all the new games are boring me, so im on this game, i get killed so bad that i have to train again, i forgot the traps !

If someone is interested making some cooperative of DM with me, send me a message , maybe what about a DOOM night if some people are intersted ?

Doom is impossible to beat on nightmare . I play this game allot, it still IMHO a better FPS game then most of todays. Most todays FPS games are not striate FPS, they always got like a RPG element to it.

I had my butt badly hurted only in ultra violence tonight , your point about RPG elements is interesting, i recently thinked about the opposite :

Tonight, chain diying on a map and falling into all the traps i knew one day the eyes closed, i thinked that DOOM had RPG elements on it, like the keys for example, and sometimes more possibilities to take many paths as in nowadays FPS, where there is always only one path, the map is like a road with walls on the sides in the FPS of today.

In doom for example we sometimes have more something like a map, where we can almost go where we want on it, i have the Suburbs map in mind here for example, with of course the condition of the triggers and the keys to not can run to the exit directly.

RPGs is the type of nowaday games that tend to have more multipaths maps.

It sometimes making us having to make wise choices of which way to take to not finish out of bullets or killed by some angry demon.

In the games like half life for example there is a lot more RPG elements but there is in addition a devolution....we always have one poor path, and most horribly, we have to search for our poor one way all the time, and to add more to this horrible concept : its a inherent part of the game, i wonder how the in game characters can evolve in a so limited space, and there are some incoherences that comes with.

I won't go more far in the bad points of the FPS of today for now, it will become off topic, an entire topic could be made about that for me, and maybe i will make one, one day.

Ye dooms amazing from when it came out i remember playing it when i was younger and i thought it was amazing but compared to games these days its nothing, but i still think some of the classics still own! nd omg yeh nightmare is unbeatable lol
