Hey, Al, interesting poll idea.
Sorry to be a nit, but it seems strange to me that something like NFS gets a whole category, but a number of very distinct games get lumped in under "nascar". My point being that NR2003 and the other Papyrus games were very respectable sims, whereas a lot of Nascar games by EA and other companies were not.
Also, if NFS is in the list, surely the old drunken standby "Gran Turismo" deserves to be in the list?
Cheers.
(For myself, the answers are RBR and GPL, but I am stretching the definition of "regularly". I used to play NR2003 a lot but LFS has replaced it in my affections.)
