I find that I've rated the Plot to Assassinate Hitler a '7'. I've played The Plot to Assassinate Hitler? News to me! (Rating deleted).
I still only have four games rated a '10' (Go, Shadowfist, Puerto Rico, and Titan). Perhaps I should add poker, which I have played constantly (if sporadically). I just realized that I've never rated 'Bridge', which certainly deserves a '10' in my book. For ~4 years, I played it more than all other games combined, and still play (15 years later).
With the new '10', my average is now 5.30. What's the average for all games, around 6? Go on everyone, rate those dogs!
