Why play Elite.....
Why not I suppose?
I personally love it for the cool apps and projects you can make with it (including a few myself!), and the time it gives me to unwind and do something fun at the end of a long day.
Then there's the community: What other game do you know of that has such a tight-knit, awesome community? I could work out this fiddly little thing in-game (and its usually possible!), but most of the time I can just ask someone and have a bajillion useful tips and guides sent my way! Or, I could make an app to read the game data and tell me how instead.
Its Options.
You have a choice! Fight, trade, explore, document (although maybe not at the same time...). Make a spreadsheet so big it won't even load!
Oh, and spaceships are cooool
