You're too easy Dutch.
Here's my $0.02 on gaming.
First I try to only buy those few games that really appeal to me and are the "leaders" in their respective fields.
I am still primarily a strategy gamer with a growing interest in good simulations.
Most games for me have about a solid 3 months of play until something else grabs my attention. With good mods and online play (especially with the Squad) this usual time frame can be further extended.

Simulations
Like many here, given the depth and love for flying WW2 planes, I have been playing IL-2 on a regular basis for almost 3 years. While I may take some breaks now and again, I can see me enjoying this series for the foreseeable future. BOB hopefully will be even more immersive and a lot of fun for the Squad!
More recently I just started enjoying Silent Hunter III, which is my first ever naval sim. I think it is a very well done game that I will probably enjoy for some time. It is a different experience than say IL-2 in that the "excitement" isn't the same, but the satisfaction of a job well done (Historic settings) I think is the goal. Wished IL-2 could create this sense of immersion. I will look at mods later on perhaps to further enhance the experience.

Strategy
Purchased R:TW when it was released, and I'm still am enjoying it (hey it's been more than 3 months!
). Best strategy game I ever played, and first Total War title I have tried.
Increasing the game difficulty, Developer's patches, a mod to make all factions playable, plus more recently an unofficial bug fix patch, has allowed me to really enjoy R:TW this long, albeit only in offline campaigns. There may be an expansion pack coming soon too!
I still consider myself primarily a strategy gamer. Looking forward to AOE III as this was my first PC strategy experience after Warcraft (original). Imperial Glory looks good too. I mostly enjoy historical-based RTS stuff, and generally not interested in fantasy or modern warfare titles (did try Matthew's Battle for Middle Earth).
This genre remains enjoyable but admittly the industry needs to add more dimension to the game play. I do like the concepts introduced in the Total War series, as I am tiring of resource building seen in so many RTS games who have patterned themselves off of the Age of Empire series.

First Person Shooters
That just leaves FPS games. Not really interested in this genre. Popular titles like Halo 2 or DOOM3 don't interest me at all.
Prior to CoD I had no exposure to this form of gaming, and was surprised how well done CoD's campaign was (though very scripted). I also like the German Mod we are playing.
Notwithstanding, I personally do find these games lack sufficient depth to keep my attention too long, as they often rely mostly on twitch reaction instead of tactical decisions.
Nothing more empty for me than a server where you repeatively re-spawn and die. Luckily, being able to enjoy a dedicated :FI: server with my mates employing team tactics (or shovel dances) has made CoD enjoyable.
Dutch I do think the BF series offers a bit of diversion and more gaming complexity should you and any others pick it up. I think I will purchase BF2 also, especially if others start playing it until CoD II arrives. It will be released next month (supposely) here in North America (so if I do get it I'll have lots of practice before YOU
).
I think more than ever the FPS developers realize that gamers enjoy challenge, and we are finding a little depth in these sorts of games.

Well, just some general thoughts about gaming. Is this post a record or what?
TactS!
Or maybe it was that I was 20 minutes later than usual. 
You mean you don't ALREADY have the beta version? Did you want me to send it to you mate? Really awesome stuff. Great teamplay, huge maps, tons of vehicles.
