1. En Garde! For those melee skirmish games. It can be easily tweaked to allow for fantasy battles, too, which would allow me to continue using half my collection of figs.
2. Black Ops Because it allows for modern and with a bit of tweaking sci-fi skirmish games.
3. Despite already saving item 2, if it happened today I'd grab Rogue Stars because I paid for the darn thing and haven't played a game of it yet!
That leaves only Gaslands on my shelf to suffer the flames. Sorry, friend. You're just too complicated for serious solo play. Via con dios.
