I love that Alien is already being faced off against two of the greatest pins of all time.....and winning!
I recently had to make this decision....I put money down on an Alien. Love the layout and the theme integration....and deeper code. Not to mention the ability to swap in other games down the road with kits.
I was also considering selling my IMVE for a AFMr but have decided to hang on to IM....I just love that game.
