Azteka and Auditorium look interesting.
How are these handled? Do I need to permanently store the installers I get emailed links to, or is it like Mount&Blade where I can download the installer whenever I want and just activate with my serial?
Preferably this would be Steam or impulse, but I doubt it :p
I am not sure but you should be able to burn them to a disk.
Aztaka is a really nice side-scroller with very nice art work and the music is spot on. I have only played the demo of Auditorium, but had a great time. It is one of the two games I do not own in the bundle.
I would say buy the games if you can, at $3.33 each it is an exceptional deal.
