Sega has posted an interview with Yosuke Okunari, Kagasei Shimomura and Naoki Horii regarding the compendium, and it has been revealed that the team at M2 has something of a soft spot for Sega's 1987 run-and-gun arcade title Alien Syndrome, and even went as far as prototyping the game as a potential addition to the collection:
KS: So rewinding a little bit, before we settled on Power Drift, we had a couple of titles to choose from for this. We talked about
Alien Syndrome, Golden Axe, Turbo Out Run, and even Columns.
NH: (looks at the lineup list) These are pretty bold choices.
– I'd like to see Alien Syndrome someday. Stereoscopic 3D would be really effective in that game.
NH: Oh that game is amazing. We did a little test on it to see how it would turn out and it was great. Although, doing every single stage would be quite an effort.
