1. The rules are read / explained quickly and you can start early with the games. Well suited for people who shy away from long control study or YouTube video instructions. The gameplay is easy and it's fun to play initially. But after a few games it gets boring - you have so the same extension integrert into play? Normal this is not so.
Short verdict: you can buy if you want a simple game and no big demands on the claim provides.
2. The waste of the claim of the games of the year since the introduction of the expert game has been extensively discussed in several reviews of "Camel Up". Now Keltis comes but from the "old" time when there were no Kennerspiel award. One year after Keltis followed with Dominion still an absolute classic and blockbuster whose cards you probably can not buy in 10-20 years (perhaps in version 3 or 4). Dominion won rightly the Game of the Year award and is absolutely no comparison to Keltis. When I therefore consider that 2008, I see Keltis and wonder: where is the question Kennerspiel this year? Should be the Agricola? I do not find. Agricola has won a special prize as a complex game, as in 2006 Caylus. Yet in 2006 there were at Thurn & Taxis, a pendent, significantly more claim than Keltis.
2014 Camel Up I sold after two games out of the horror of the award in spite of banality and unpretentiousness immediately.
2013 Hanabi is quite nice but no more. Due to the low price and the unusual game concept I have to keep it.
2012 Kingdom Builder is a game of the year, as I imagine it. And that in the Kennerspiel phase. It really works!
2011 + 2010 I have not tried, here I have the Banaltät probably already smelled.
Conclusion: I would no longer buy Keltis. Since I'd already have it but keep it though - but I have already a few games muck behind which I am not 100%. And since Keltis unfortunately fallen victim.
Ever since Camel up is clear to me: No Blind buying games of the year with no previous test match more.
