I stopped gaming completely since I think it just not worth the time.
Games that I played and liked a lot are: (these ratings are not over the top. They are exactly how I think about the game)
Without so much doubt one of the best games ever made. Great graphics and gameplay. A game which is most likely more balanced than any other real time strategy game ever made. If any game deserves a 10 this is the one.
Quake(1/2/3): (9/10) (Netquake/ Rocket Arena/ Defrag/ CPMA)
The quake series has been fun to play and quake 3 still is a great game. It is too bad that quake 4 is not good at all.
Great games. All of them. In warcraft 3 the multiplayer aspect was great. It will however never be something like SC used to be.
Dota(ums in wc3): (7/10)
Needs a lot of developing still but it is getting bigger and bigger. And please don't tell me DotA is a game for people that are not skilled enough to play regular wc3. If you think so you should try and enter some games where people are more skilled. (no pubs)
Now for some classics: (you will need DOSbox or another emulator if you want to play them)
Monkey Island I & II: (9.5/10)
A great and funny adventure game which has been made more than 10 years ago. If I would play it again I am sure I would like it again. Awesome graphics considering the time it was made.
Simon The Sorcerer: (9.5/10)
Another game, very much alike Monkey Island. You play a young boy who ends up in another world.
Final Fantasy: (8.5/10)
On average the FF series was really good. I enjoyed played the first part a lot when it first came out. Now, however the first game is really boring and will take up a lot of your time where you will be wondering why you are even playing this game.
Dune(1/2): (8/10) (you should really read the book)
The first part was great. Even more so than the second part which was a real time strategy game. (the first one was an adventure game) I played this for way too long.
Well... It had to be on this list. There is no way around it if you have CK as your avatar. This game is great for kids. I really enjoyed it as a kid. Now there are better games available in the same genre.
The list goes on and on. And so does the time. I think I mentioned the best games out there. (according to me) Please do not pm me if you disagree.
