Realms of Antiquity: The Shattered Crown

The Good
Classic 80s RPG goodness in the style of Ultima, etc, with a lot of modern comforts and improvements. A large world to explore with incredible variety, nicely and believably divided into digestible-sized areas to not feel overwhelming.

The Bad
There is no sequel planned.

The Bottom Line
A true labor of love on two levels: not only is it an amazingly complete ultima-esque 80s-style RPG that ticks all the nostalgia boxes, while also avoiding the negative aspects of 80s gaming with various UI improvements and conveniences, but also, the whole thing runs on a TI99! This makes it perhaps the only actually really good game ever made for the woefully mismanaged and short-lived TI99.

Definitely worth a look for any fan of 80s-style RPGs, and as far as I'm concerned it's right up there in the top ten.
