Doom and Hexen for PC.

Contra for my NES. (overall oldest)

STARCRAFT

Believe me, Still in my computer... I haven't finished it yet......

For me it's Starcraft and Caesar 3 lol.doomsdaydave11

Hey I still play Ceasar 3 every now and then too!

Funny you put this topic up today.  I just loaded up Fallout 2 lol.  I bought it a year ago and tried playing it, but just couldnt get into it for some reason.  Been playing it for a few hours today though and its quite fun...just requires a bit more patience than I am used to, thats all.

Some other games I play are:

Dune 2000: sure, its an update but its still the original RTS that came out in 1992.
System Shock 2
Deus Ex
C&C: Red Alert
C&C: Tiberian Dawn
Caesar 3
Pharoh

X-com Terror from the deep

Burntime

Jetpack

Black Thorne

Super speed

hehe, play all these on good ole dosbox :) 

Sonic 2, Sonic 3 & Knuckles

haha minesweeper. awesome.

but also Dune 2. I've played it so much I can finish the last level for the Atriedes with just the units I start with.

X-Com and Star Control 2...

Grand Prix Legends (1997)knut-am

Best racing game ever. On any platform. 

Caesar 3 and Civ 2

well on monday i played.

 total annihilation (1995)

games still a classic big bertha galore!

I still sometimes play Kings Quest VI.Batman_Begins

YES!!! That was the best game! XD

For my my oldest game is probably Tempest. Sure it's ancient and todays kiddies will have no idea what they are looking at on their screen if they were to load it up, but I've loved since it first appeared and still feel it's as addicting as ever. 

NFS porsche unleashed (2000) - undoubtedly the best NFS n racing game ever 4 PC. this game isnt s easy s when u play NFS underground the first time.no doubt this is the only SIMULATION version of NFS.

the operative:no one lives forever (2000) - the best ever n most unique heroine FPS ever with a combo of james bond n austin powers settings.the storyline n long cut scenes plus retro music score is so awesome just like u r watching movies.

max payne (2001) - i like the BULLET TIME n dodge shooting with dual pistols n ingrams.the 2nd dream sequence level can be super scary at times n if only there is a way 2 skip this level then it would be great because i hate 2 go thru that level again.

soldier of fortune 2 (2002) - IMO this is the most all round FPS of all time.from the city of prague to the jungles of colombia.then to the city of hong kong n the finale in FBI headquarters in texas USA.its just so beautiful going around the world doing different op missions.the weapons r very realistic along with the ultra violence where u can decapacitate the enemies limbs with a shotgun n grenades.modern FPS of today cant really match the features of what SOF 2 has offer 5 years ago. 

Blood 2 the chosen - excelent fps with great story line and dialogue

lol, nice timing with that topic. actually i started wizardry 7 (anyone knows how to identify

items, i dontmean assay but to see dameage of weapns for example ?)

btw king quest is that an adventure game or rpg ?
