Is this the original or revised edition?

This is the revised version. However, if you get the expansion only the investigator cards will be duplicates. The Outer Worlds and Adventure Cards in the expansion update those cards with new features from the expansion.

Offhand I have no idea. I purchased mine about 6 months ago and the instructions looked like a first edition run. Contacting the seller may give you the specifics as to what they have in stock. There are some vagaries in the rules, but I found online errata to help with any confusion.

You don't need 1st edition. The 2nd edition is a complete stand-alone replacement. There are a few mistakes in the rules regarding victory cities and scoring (at least in my copy). Avalon Hill has the errata posted online; I'm not sure if the corrections actually made it to print.

The box just says "new edition." It doesn't have a number listed. Obviously not the first edition, and it doesn't have the expansion, but it has some nice features like life-point bullets and organizer cards to keep everything tidy.

Yes. Although this is the older version of the game, there is a new one out.

The second edition actually fixes some of the random issues with logical inconsistencies (in the first edition you could have a lake on the second floor), and it clarifies some of the scenarios while adding and removing a few of them.

This is the over clocked edition, plus when I got it, it was cheaper than it is now. I also had quite a few discounts. It ended up being 450.

No, it is a cheap copy. It works, but it is much fainter than the original. I will have to buy a genuine one elsewhere.

No, the difference is not significant. At this point, buy whichever version has the cheapest used copy available.

It appears to be the original. I haven't had any problems with mine so far anyway so I'm happy with it.

Revised is the reprint with full color art. Apparently the old version didn't have full color. Also may have some rules changes.Source: http://www.sjgames.com/general/press_releases/100514.html

I started with the second edition and had no hiccups so I would say no. It is just a revision not an expansion.

It is neither. The yellow edition is the original edition. The party and family are separate editions.

I just received the 2nd edition. This includes the new 4th edition compatible colonies.

No it is not, I was very disappointed to get the new version, not the original

No, not so far as I am aware? This is the old classic. When I get a chance, I will open it up and again and take another look though just so you can be sure.

Im not sure what you mean by 'original' game. We imported it from the USA to the UK so would not know if it was updated or not, sorry. We have a lot of fun playing though, it becomes addictive and what starts off as a couple of games ends up going on for hours!!
