Wow, this thread brought back some memories! I'm 55.5, so I go back to the early days - i.e. Pong. One of my brothers bought one of the boxes that would only play that, lol - got boring pretty quick. Also had a TI-99/4A, Atari 2600, Intellivision, Atari 130xe, Sega Genesis, PC, PS3, multiple Xbox and a Wii U.
I always liked PC games the best. I remember playing an early 90's turn based strategy game with a friend over modem! What a pain in the ass that way but it was revolutionary. Can't for the life of me remember the name of it though! It was sort of like Risk, oh well, I'm getting old. Maybe it was Command HQ? IDK.
I played lots of Wolfenstein and Doom, tons of Master of Orion (I loved the 4x space games)! Then came CnC Red Alert (see my avatar lol), CnC Generals, Total Annihilation and other RTS until Unreal came out. That game was a serious time suck for me, I used to play it 4 hours a night and was in one of the top clans and went to a couple of large LAN parties, lol how silly now that I look back! Didn't like Unreal Tournament as much but played it a good bit, also lots of Quake 2 - that game sure got your heartrate pumping heavily! Then Unreal 2 was pretty fun, but not as much as the OG Unreal.
Battlefield Vietnam was fun for a while, tried some of the newer BF's afterwards but none sucked me in quite the same. Struggled through WW2 Online for a while, was fun but glitchy as could be.
Probably forgetting more than a few! As mentioned above, I've had 3 Xbox but never could get into them - everything bored me to tears.
