1. The First game I played on a computer would be "Dungeons of Daggorath" on a TRS-80 with an amazing 16k of RAM. Loved the game but hated that it took me forever to beat it (I didn't have a cassette player to hook up to it and save games for a long time) I think it took me 3 hours to beat it in one sitting the first time.
2. wow, hard to pick 5, but I'll try.
When my brother and I were real little, it would have to be COMBAT for the Atari 2600. and the hours we spent trying to make "pool shots" off the sides of the screen to kill each other.
When I was young and my dad splurged and bought a tandy 1000SL PC, I'd have to say it was Civilization. I spent hours upon Hours getting nukes and taking out Ghandi.
As I got Older, I went on to Ultima 6, because of the involuted storyline, and it took me forever to finally figure out how to put that damn balloon together.
My first Online game would have to be "Rites of Passage" which was an all-text D&D type role playing MUD (Multi-User Dungeon) of good vs. Evil. It was a rush to get a group and kill a couple of "Evil" characters making them lose their equipment.
And Finally Aces High, because I've loved airplanes since I sat and watched TORA TORA TORA, Midway, Black Sheep Squadron, and all those movies with my parents. AH lets me Fly, try to shoot someone down, and die in the process, loving it every time.
I'll do the honorable mentions list too:
Battlehawks 1942: My first airplane game (and it only fit on one 3.5 low density floppy!) god was I addicted to that one for a while
Red Baron
Wing Commander, All of them
Pirates!
WB, because that's what started me flying online
<S!>
Hamish!
