Dominion - Oh dear. I might be addicted after one game. Dominion's all-too-easy ABC* deckbuilding mechanic allows you to try out new strategies on the fly, as well as eagerly anticipating what the next hand might bring. Once your deck is as fat as your fist, then the game picks up a ferocious pace, with everyone frantically throwing more amazing combos on the table to pick up more gold, more cards, and most importantly, more of those victory points. It's interesting to see the game start slow, as you sludge through the first few buy phases. Even so, the available supply you can purchase from can be customized with every game, making those expansions all the more enticing. I shudder to think of the day when I own them all.
