Tail of the Sun was an open-world caveman simulator in which you gathered supplies
for your tribe and for yourself, hunting and gathering during the day, sleeping
at night, ever striving to increase your personal attributes while you fought
off hostile animals and competing tribes of apes. As you progressed through the
game, as you increased your intelligence and collected resources, your gains
were inheritable in that, if you died, you continued your quest with another
clan member. Your clan’s ultimate goal if, as a tribe, you survived to see it
through to its finish, was to build a tower of mammoth tusks to the sun.

Carnage Heart was sheer genius; a strategy game in which you not only assembled
your own mech, choosing between either lightness, speed and high mobility or armor,
firepower and limited mobility, but you also had to program your mech. The
interface included dozens and dozens of partially pre-programmed “chips”
that carried within them basic instructions — “turn left,” “turn
right,” “scan” and so forth — that you were able to then tweak as
you saw fit before inserting the chips that you’d selected into a “circuit
board.” The circuit board controlled your mech’s behaviors using your programmed
sequence of predetermined movement and action decision trees. You would then
send your mech out into the game world; whether you progressed through the
storyline depending entirely on how well you programmed your mech. As you
advanced through the storyline, your mech’s A.I. also advanced as you, in the
role of programmer, developed increasingly complex exploration and combat behaviors.
