C64/128: Apollo 18 CIB?

[cyberfluxor]

I picked up a copy of Apollo 18 today for a few cents at a thrift store. Without a system or a known working 5.25" drive in my possession I'm not sure if the data is okay. Now what it has is:
1 disk, manual, box with an intact infold, and addendum print-out.

The game isn't on eBay and there are a few out-of-date retail listings scattered across the net. Apparently it's not listed in the rarity guide here and am unaware of other guides, however I've read of those communities existing on here before. But the questions are, is this complete and how significant/rare/valuable is this game.

I'm sure Flack will pop in as apparently this is one of his favorite C64/128 games.

Not really rare... you might get $5-10 for it on eBay if complete.

I appreciate the estimation Mayhem. No plans to sell it off since it's my only C64/128 game and is a computer I'd like to own. For whatever reason I don't see much Commodore stuff around here.

So any other takes on pricing, game play, or any special attributes about this game? Complete or no?
