The Witcher

You mean the game that got mediocre reviews at best or are you telling a joke about how PC has no good games?

i don't follow game reviews much anymore ,but out of my own experience i enjoyed the game a lot, it was fun and you can never go wrong with point and click games.

......And Dawn of War 2 is better than COH. Both games arent traditional RTS's, they are squad based RPG/RTS's.

At the moment I am loving STALKER:Shadow of Chernobyl. On the other hand I have not yet played Fallout 3, so Im not sure how they compare.

recommend me  is asking for someone to recommend you for something or to someone.  If you want someone to recommend something then you need to say recommend XXX to me.  it is simple grammar. 

People didn't get it right.  They actually got it all wrong.  Everyone posts this recommend me crap, and it is annoying. 

I much prefer the WW2 setting which is why it gets my vote

If you have any questions about the games I'm suggesting please feel free to ask.

Jade Empire

RPG made by BioWare, I consider it not as good as other BioWare games, but it's still fun. The world is based on Chinese mythology. You can learn different fighting styles, varying from martial arts, weapons and transformations. The story is very good. The downside is that you can only have one follower at a time with you and they are fairly useless, they either attack your enemies, they mostly work as distraction, or have them on support which varies from character to character.

Steam has it.

Overlord series

It is similar to Pikmin, you are an Overlord and control an army of minions. You improve health, mana, spells by finding relics and bringing them to your base. You're character can also participate in the fights.

King's Bounty

Mix of RPG and TBS. You can move around the world in world in real-time, while the battles are turn-based. You can have a maximum of 5 units, and 2 reserves(they don't participate in the battles). You gain skills by spending runes.

Vampire: The Masquerade - Bloodlines

It's an action-adventure with RPG elements. You play as a newly created vampire, and watch as your sire is killed and then you become the lackey of the ruling vampire of Los Angeles, or so he'd like to think. The world is made up of hubs, most tasks can be accomplished in several ways. There are two things to take into account the Masquerade and Humanity meter, if people see you feeding or your powers you lose a Masquerade point, this means that vampire hunters are likely to appear in the overworld, loose too many and it's instant game over. You lose humanity when you kill innocents, I use the word loosely. With a low humanity score the chances that you succumb to the beast when at low blood levels are high.

You can choose to be vampire from 7 clans, Brujah is a very good choice for a beginner, very good at melee fighting; Ventrue, manipulators; Toreador, also good for beginners; Tremere are blood mages; Gangrel, wolf-men, sort off, would not recommend for first playthrough; Nosferatu, calling them ugly is an understatement, not for first playthorugh as you mostly have to use the sewers; Malkavian, they are insane but have insight, and will spoil some things.

Finally if you get it I recommend getting one of the fan made patches, the game has a lot of bugs.

Ghost Master

In this game you play as a ghost master, you place ghosts in the level world and can assign what powers they can use, you do not directly control them. After finishing a level you get gold plasm, the amount depends on several factors, which you can use to buy new powers for your ghosts. The objective is usually to scare all the mortals away. And in a level you may find ghosts which you can recruit if certain conditions are met.

Steam has it.

The Longest Journey series

Point and click adventure games, the story was very good in my opinion.

Syberia series

Also point and click adventure games. The world is rather steam-punk and the story was nice.

Broken Sword series

Point and click adventure games.

Hostile Waters: Antaeus Rising

A mix of shooter and strategy. You are the captain of a ship that can build vehicles from scrap, you're crew is not alive but rather their memories and minds have been placed on chips. The objective is usually to kill the hostiles on an island than move to the next one. There are several vehicles you can make and can choose what weapons and upgrades they have.

@ Rhonin the Wizard, about Jade Empire; is that a real time battle system? I'm playing KOTOR at the moment, so that was the next game to play logically, but if it is more of an action RPG, that might put me off

Yes, it's real time. The action in the battles are a little fast. Though I liked that since it reminded me of kung fu movies.
