I love how letterpress is really a territory game disguised as a word game. Instead of rolling a dice like you do in Risk, you find words to form your attacks. Rather than trying to pick up words with obscure letters, or lengthy words, you try to capture strategic tiles and expand your controlled area. Once you cover a large area of dark blue tiles, you choke out your opponent's ability to score points, and the game slowly snowballs further in your favor. It's really fascinating.
Also I like how you can attack and defend simultaneously. If the opponent goes first, then they'll stake out a corner. And then I will attack their corner and stake out my own corner simulataneously, as long as there's a big enough word on the board.
