Haha, I already own all those (great) games (except Aquaria).
But I bought it again, to support you!

And this way I'll have DEFCON & Darwinia soundtracks too.
And I'll play with you tech demos (cool move).
I wish you the best!

Welcome to those 2 little Introversionians. :D However, you'll soon realize that there is no 'pause' nor 'undo' nor 'go to sleep' working commands on those models. The 'upgrade' command is available but very slow. But that's what creates a fun and maybe sometimes repetitive but often surprising game...
