#1 could be Dink Smallwood.

Not it, either, but that is a good game. The graphics weren't that good, I don't think. Nor did it had that pseudo-3D feel.

There is another game I wanted to suggest, but I can't remember the name.

It was a very cheesy game, could not stand it. It had something to do with hex or hexagon in it's name, and it's a dark and forgotten game.

That doesn't ring any bells... The only thing that makes me think of is Hexen, but that's an FPS. And also not cheesy.

I remember it now. It was Hexplore.

Wow, you weren't kidding when you said cheesy, huh? Still, it looks like it could be amusing for a little while. I'm sad to say this isn't it, either. This looks too new... Also I remember controlling only one character.

i don't know how the game itself is but on the screenshots it actually looks kinda fun

Good news! Using the MobyGames browser, I found out what #3 is! It's Take No Prisoners.

No such luck for the other two, even using the browser... Ah well!

I just found #2. The game is called 3D Dudes. The developer seems to have dropped off of the face of the planet, and all internet downloads seem to be only the shareware version. Although according to most sources, that's for the best since this apparently was an absolutely atrocious game. Still, I remember it from my childhood and it makes me sad that I can't dig up the full version... Or run it with Vista.

#1... I don't know. It COULD be Wraith I'm thinking of. But... Even after playing the shareware I'm not absolutely certain. How stupid is that? I can remember playing a game, but I don't even know if this is the same one. Maybe I made the game up. I don't know, this SEEMS to have similar gameplay and a similar inventory system... And the character creation seems familiar (then again, I played pretty much every one of the games on these "1000+ Great Games!" CDs, so a lot of stuff is familiar), but I could've sworn that the game I'm thinking of has larger sprites for characters and is a top-down view, not this pseudo-3D stuff. I also remember it being more... Cave-like. And fighting some kind of green enemy, though I can't remember if it was a lizard, an orc, or something else entirely. I'll try to find a full version of this and play it a bit more, but in the meantime feel free to make more suggestions.

Also, thanks for the previous guesses guys.

Hmm, what about WarWizard? It was released for Ms-Dos also.
