generally, ive played all the exile/avernum games with a singleton...
i got excited with nethergate, as it seemed there was no upper stat limit (like the max of 20 on the old exile games) so i figured it would be better for a singleton.
anyways, ive gotten as far as formello with two different singletons, and it takes a ridiculous amount of reloading, and hoping for lucky random number generations...
i dont know if it's intentional or not, but it seems like the avernum series has been leaning away from the whole idea of a singleton party.
too bad, cause thats one of the things i really liked about the exile/avernum series, is that it didnt force you into classes, and it let you play with as many people (up to 4 or 6) as you wanted.
oh well. guess all good things come to an end...
