Really hope that Midway disc comes to the US. I already bought Robotron from someone on another forum, but Smash TV alone would be awesome. Other possibilities (other games once available and now removed) include Gauntlet, Joust, Cyberball 2072, Defender, Paperboy, Tapper and UMK3 (unlikely with the horrible Arcade Kollection already available). Quite the list there.
Unrelated, but I added Feeding Frenzy 2 to my backlog just now. Have 200/200 on the first and am looking forward to plowing through the 2nd one when I hit my backlog hard next year. I think I finally own all the PopCap games I have any interest in. (FF 1 and 2, PvZ, Heavy Weapon and Astro Pop).
