Leisure Suit Larry was created together with Police Quest 1, as a new addition to the adventure genre.
You are Larry Laffer, a 38-year-old loser who has lived his entire life at his mum's place. One day he suddenly realises that he needs to live the good life and taste the forbidden fruit, so he goes out and buys a leisure suit and some gold jewellery. The old Larry Laffer has died, and the new one is ready to get down and boogie!
The plot of the game is quite simple: you have to score with a female within 24 hours.
This game is great fun, and it kept me busy for a long time when it was released. Considering that I was about eight years old when I first tried the game, it is a miracle that I actually managed to complete it. (My English typing was quite basic in those days, to say the least). Thankfully my older brother stepped in and helped me type such difficult commands as EXAMINE and GIVE WHISKEY TO DRUNK. Basically he did almost everything in the game the first time I "played" it. Thanks, man!
This game was the first of its kind to have sequels waiting. Al Lowe had designed Larry to evolve throughout the games, so the story of Larry is more complex than the story of many other game heroes.
There is not much more to say about the first Larry game. It was meant as an introduction to the "quest" game style, although it is very different from the other three series (King's Quest, Space Quest & Police Quest).
Have fun with this little gem.
