Not my first but one of the earilest game I can actually remember beating would have to be the first Tomb Raider
Space Invaders, Missile Command, and Pac Man didn't have endings! I think I have to go with @I Will Haunt You 's answer and pick Adventure on the Atari 2600.Did you even know games had endings when you were a kid?
My first game I recall finishing was Wasteland, needless to say when Fallout and its line especially Fallout 4 came along I was completely hooked.I ask the PCG staff a regular Weekend Question and post the answers on the site. If you'd like to throw in an answer here, I'll squeeze the best into the finished article!
This week's question is: What's the first game you remember finishing? Did you even know games had endings when you were a kid? Have you always had to finish one game before moving on to the next?
Ya know... Don't think I ever really finished it. Just spent countless hours making maps on graph paper. Those were the days, am I right? If you don't know what aim talking about then you must not be a true PC Gamer... or ... Maybe I'm just dating myself. Live Long and Game Often my Friends.Zork
