Eclipse is the best board game ever!
Catan is far to repetitive (I'll state... for me...here).
Nice to see Armada is doing well, honestly I do not understand why retailers keep the base game priced so high comparatively to online retailer prices, yes they have potentially more overheads, but my local shops have probably had the same stock in, sat there for the better part of a year, surely selling it for £20 less and shifting a few dozen, is better than 1-2 per year.
How many board games have you played? Plus have you played War of the Ring...how about Merchants & Mauraders, Forge War, or Clash of Cultures. Eclipse is great, but not many people hear have played 75% of the top rate games to make such a statement. I would certainly put War of the Ring & M&M before Eclipse and I would also say Forge War is almost as good if not better as it needs more plays. Clash is either tied or right their or just a notch below.
Point being there are too many games now out there in the top 300 games that really can be labeled best. Oh and I forgot Twilight Struggle ...wow what an awesome game...also better than Eclipse with the right opponent (someone of roughly equal skill).
