One of the main purposes of the Pandora is gaming. It has dedicated gaming controls (a proper D-Pad and buttons - some things most devices nowadays are missing).
It is powerful enough to emulate Amiga 500 games in fullspeed so you can relive your past. Of course, older computers like the C64, the MSX, the Atari ST, the Spectrum, etc. can also be emulated with ease.
It can also emulate classic video game consoles up to (and including) the 32bit generation - and even some 64bit consoles!
Another way to relive your past is by using rewritten game engines. That way, you can play games like Ultima VII, Baldur's Gate, basically all classic Point-and-Click Adventure games, classic Text adventure games, etc.
But there's more than just retrogaming:
Thanks to the growing Linux community, there are great games like Battle for Wesnoth, FreeCiv or NumptyPhysics.
And there are also a lot of homebrew developers, releasing games like Panjoust, Gianas Return or Pandora Panic.
