Hey, timyo, n00b here.
first off, Tiggit is a dream come true. Please Please Please continue this. I've searched so many times for freeware games its crazy but this makes everything soo much easier.
Anyway! Just though Id suggest a couple of sites I know that have a bunch of free legal downloads:
Whole bunch of dos games and all for free download. Some freeware, some shareware, some demos. really really great place.
Another great place with tons of freeware games.
And for some games:
Elder scrolls 1 and 2
and gauntlet revisited
Hope I haven't repeated anything, I'm not really a forum guy, but I wanted to express my Extreme interest and some suggestions.
Thanks and Please keep it up!
