HoMM5 is okay for short play periods, King's bounty the Legend is okay, havent played armored princess. Civ 4 obviously is great. And Gal Civ 2 isn't too bad if you can get past some of the glaring flaws in the design.

Games im playing now = Elemental, Starcraft2, ARMA2/Operation Arrowhead, Dawn Of DSicovery, Forza3 and Team Fortress2 (just finished mafia2 also)

Some of my all time favs = Wizardry series, Kings Bounty, Dune2, MOM, Simcity series, Age Of Empires, Total War series, Police Quest series, Final Fantasy Tactics, The Witcher, Baldurs Gate series, KOTOR, Mass Effect1/2, Ultima series, Half Life series, Diablo2, Divine Divinity, General Chaos and Galactic Civilization

Ah Wizardry, how I miss ye

Proving Grounds of the Mad Overlord (aka Wizardry I) was the 3rd computer game I ever got way back in 1981.  I still have incredibly fond memories of those line drawn dungeons.

Space Rangers 2. Best game ever imho.

I'm currently playing Pathologic. Anyone who thinks Elemental is bad ought to try that, it's the only game I know that keeps you playing despite the fact it's impossible to enjoy it.

Or try Gods & Generals. I tend to find playing that puts an entirely new perspective on just how bad a game can be.

Old or new?

New, I have found that King Arthur - The Role-playing Wargame is pretty damn fantastic. The company is VERY small (I think around 5-10 ppl), and similar to Stardock they keep updating and adding content. Just an outstanding game. If they had city building it would give Elemental a knock out. Just a shame that Impulse has no multiplayer or the downloadabul content, so I had to buy in from Steam.

The complete Baldurs Gate series is just untouchabul, I doubt anyone will manage to creat a better roleplaying game than Baldurs Gate II.

Temple of Elemental Evil I also enjoyed a lot, but never finished it.

Evil Genius is a hell of a lot of fun.

Sins of a Solar Empire

Plants vs Zombies

The Witcher

Mass Effect I + II (the story ONLY! I didn't care much for the gameplay but the story kept me going)

Meh, I could keep going and going...too many great games out there.

Things I've liked a lot are:

More or less everything from Bioware.
Supreme Commander 2 (With a nagging feeling the original was better)
Empire+Napoleon Total War
Mount&Blade: Warband
Battlestations Midway/Pacific
X3: Terran Conflict
Divinity II - Ego Draconis
Civ IV: BTS
Company of Heroes
Sins of a Solar Empire
King's Bounty: Legend / Armored Princess
Silent Storm
Jagged Alliance
MoM
HoMM 3,5
Borderlands
Grand Theft Auto IV
Trine

.. and probably a lot I can't remember at the moment.

But honestly, I've liked a lot of games that has gotten fairly bad review scores - while they are not all time favourites, I've played through Hard Truck Apocalypse, Spectromancer, Tank Universal, and other indy games that has been very good, despite - at times - glaring flaws. I can look at a game and say 'Hm, that (and that and that) bit could be better' without going 'the whole game sucks donkey somethings' - as long as it brings something new or different to the table. There is so little risk-taking in high-production games that PC games are evolving into a paraphrasing of that old joke: "What kind of games do you play here?" "We play both kinds - shooters and RTS". SC2 is a good example of that - polished so it shines, but the gameplay is identical to the original. A few new units; that's it. And it still sells by the barrel. Played it a couple of days, then played a bit multiplayer, haven't touched it since. If you want anything new or different, there's a few daring developers, the rest is Indy games. And those games are renown for having glaring design flaws... but it's something you will have to put up with if you want to play anything other than A4 RTS/Shooters.
