I've set the games to email me when someone achieves a respectable score in one. I still occasionally get one of those emails. That's LSL (Linden Scripting Language) code that was compiled into bitcode years ago and the source hasn't been touched in any way since, and neither has the bitcode (or the script would've been reset and lost its memory - all the highscores are stored only in script memory) - and it still continues to run. This amazes me. That's the kind of stability many webhosts can only dream of.
Oh, the SLURL is on the bottom of these emails if you want to check out some really old games: http://slurl.com/secondlife/Stillman/65/81/24
