I have to admit I 've always been a bit of a sucker for macro-simulation games, but the problem is eventually after many many hours of playing, you build everything within the technology ladder.
This accounts for games like Simcity, Civilisation II, Alpha Centuri, Acendancy, even games like Constructor.
Admittedly Games I could never get the angle on were ones that involved a joypad and high speed precision button pressing (I have this theory that the taller you are, the longer it takes you to push the button, so your timing is always off... resulting in the annoying humilation of getting your butt whipped in Mortal Kombat, Tekken (add a number here) or even the old Street Fighter II.
Many a time has some young scruffy rascal of a kid whipped me into submission within the confines of an arcade. Okay at home you can take it.. it's the on lookers and the realisation that it's going to take an eternity of playing to get the little rapscallion back)
Such games as Quake, Half-life and all First person perspective shoot-em ups.... Well, it can get a bit annoying... Take for instance... the toilet in Goldeneye... don't you just hate it when you get shot.. reappear in the vent shaft, and everyone in the multiplayer makes a beeline for the toilet to stake your exit out.
I couldn't get enough of Grand theft Auto. Although GTA2 had some seriously tough red payphones to deal with... (It's a pitty my machine wasn't nicer or I would of got it on a PC platform to multiplay)
Command and Conquer/Red alert /My missing Tiberium Sun (and the add ons and most recent version) are by far the most played.
Although DARK REIGN II makes use of 3D, and you can change camera angles, and if your machine is at ultra high specs the graphics improve. I had some fun with this, it's far better than it's original Dark Reign counterpart.
DARK COLONY... This game is a few years old, but it's basically a bunch of marines is taking on a GREY alien invasion... and boy do the little suckers scream as you rip into them with a gun.
(feats blood splatters)
SYNDICATE/SYNDICATE: American Revolt/SYNDICATE WARS....
This is what I want to see get reborn once more, with yet more style.. The original Syndicate was written purely on the Amiga, and the Second began being written on the Amiga and halfway through they changed their mind and moved it to the PC.
I still love the way in Syndicate wars you can keep Guassing a spot on the map and make a serious dent and the use of the scope rifle always came up with satisfying results.
Commando's... Okay to begin with you pull on your hair... the enemies tend to spot you as you learn the tactics and your mens faces get skulled all too quickly.
GANGSTERS (Message me if you ever want a multiplayer

) I think this game is brilliant... Build up a Mafia, control a section of city, run numbers rackets, and printers you place in the allyway a counterfitting operation, and if your really crafty you get to set up a cat house.
Not to mention the gun battles.. walking into enemy territory with 6 people and opening up with dual pistols and tommy guns, Watch out for the irish police though they tend to get a little upset when a few of their collegues get plugged in the crossfire.
If your really lucky, your extortion racket will last and you'll end up with the mayor on your payroll.
HITMAN: Codename 47
This was an ultimate in first person (I think MAX PAINE beats it now) Your allowed out of a funny farm.. after being taught how to handle yourself, and get ready for your new line of work.... Your the force behind dealing with problems.... covertly... and pretty much illegally.
Okay some might find sneaking behind a person and grotting them with pianowire some sort of kick, but stripping a dead man of his clothing and dragging him into a dark corner... that's almost queer.
DIABLO I/II
One is fun in a multiplayer, but II is suppose to be more fun... Pity my system has those BSOD (Blue Screens of Death) at Regular intervals... usually when I'm about to get a really decent item, or just killed a boss.
