I really enjoy Attack from Mars and its one heck of an awesome game...but I personally cannot see spending $8k plus another $400 for a color display update (even if its included for $8k I would still pass). If the game included a new set of rules and color changing LED's I would consider it. Having the option to select between the original ruleset and a new ruleset would be an awesome feature for these remake games and help justify the price.
For $8k-$8.5k there's multiple new games that offer more rules, features and value. For the price of an Attack from Mars remake I can buy an Alien LE with powder coated armor, lighted ramps / lighted side art, 27" backbox display, playfield LCD (well 2 of them), color changing GI and color changing inserts.
It will be interesting to see what the actual price of the AFM remake is and if there's going to be an increase from PPS for this one.
