Must-play classic PC Action-RPGs

So, I've been playing through the original Deus Ex recently and it's been absolutely fantastic. I really want to play more PC games like it, because I have never been into PC gaming. I'm saving CRPGs for next summer (I've got school to think about), but I'd like to know what Deus Ex-ish games that you guys would recommend (or any other classic PC non-CRPGs that I shouldn't miss). I've already got Vampire The Masquerade Bloodlines & System Shock 2 lined up. I tried to get Thief & Thief 2 to run on Windows 7, but it was an absolutely massive headache that I'm not sure I want to mess with.

From the top of my head: Alpha Protocol.

If you didn't play S.T.A.L.K.E.R. like you would normally play Thief then you were doing it wrong. Stalker brutally punished you for getting into the thick of action.

If the OP was talking about classic action RPGs he'd start with Zelda and work his way up. It sounds like he's young enough to only like FPS style RPGs so he'd be more suited to getting a copy of Morrowind.

Excellent choice with VTMB!

Ultima Underworld 1+2

Diablo 2 is a must in my opinion, although it's not really 'Deus Ex-ish'.

System Shock....1!

I don't see how anyone can recommend Alpha Protocol with a straight face.
 
The Jedi Knight series, while less RPG have always been fantastic (just don't play Jedi Academy)

You mentioned you have it already but Vampire - Bloodlines is seriously good.

I'd also suggest Elder Scrolls 3: Morrowind.

@Rawrnosaurous: I enjoyed Alpha Protocol a lot.. The story had a lot of problems and some of the gameplay mechanics were pretty wonky, but it was as close as we had to a new game like Deus Ex for quite a long time. Plus it does the moral choices/consequences thing better than any other game I've ever seen, the game dynamically changed a LOT of the story and conversations depending on what you would say during conversations and even what you actually did during the missions, it was really well done.

I second the System Shock series

@Rawrnosaurous: In fairness, they've always had to work under extremely tight time frames. Blame Lucasarts for releasing KotOR 2 before it was finished, not Obsidian for developing it.

The writing, story and many of the gameplay mechanics were far better than the originals. It was only ruined by the bugs and.. the lack of an end. Alpha Protocol was very similar, Sega rushed the game because they wanted it out quickly and then even after it was delayed to miss the holiday period, Obsidian weren't allowed to work on any of the problems, they literally just sat on it for months.

I think they're one of the best developers out there. Publishers just use them to quickly farm out sequels to their big AAA games.

Developers in the last two decades in the west.

Define classic? I've spent countless hours in Fallout: New Vegas, I'd recommend that. So much to explore, so many ways to solve a given problem.

@Rawrnosaurous: Like I said it was delayed simply to fit a better time frame, they weren't working on it during that time. They had little more than a year to make Alpha Protocol. Lucasart's treatment of other developers speaks for itself.

Look at some of their good work in comparison, such as New Vegas, which was easily superior to Fallout 3 and was much closer to the style of the original games.

Again, I think they're a great developer that are just treated poorly by publishers. Others may work under timescales too, but you're not going to see Bioware rushed that badly to create ME3 and then have it released before it's actually done.

I don't see how anyone can recommend Alpha Protocol with a straight face.

Baldur's Gate 2...still my favorite all time game.

Try NOX by westwood studio. i just started playing it and it got me back into these games.

I don't remember if they made it for PC or not, but Project Snowblind was an awesome Deus Ex clone.

Anyway

STALKER

Fallout 1-2

Project Snowblind is an FPS that actually started off as Deus Ex game. Off-hand I dont remember why it wasent a Deus Ex game, I guess in case it bombed like Invisable War, but there is a reason a lot of the stuff looks stolen from Deus Ex :)
