The title says it all. FBG:TSS is pretty much a pointless game to show a template for other F.B.G. mods.
FGB:TSS is a mod primarily composed to be a template for all other F.B.G. mods, or other folder based games, which technically count as mods. It is not really a game with story. Again, it is just a template for all other F.B.G. mods.
