The youplay.it site is working again after being down for 2 days and 18 hours! For those of you who don't know, youplay.it hosts free online versions of Blue Max, Cartagena, VampiRing, King Me! and Wooden Ships & Iron Men.
My favourite game is Blue Max and I've played over 900 games in the five years I've been registered on the site. Blue Max is a game of WWI air combat where players pilot an aircraft with the aim of shooting down their opponents. The game is played on a hex map and each type of aircraft has different move capabilities. Moves are simultaneous so you never know exactly which move your opponent will choose, but based on their previous move, speed and extra information you may receive if you are tailing them, it is possible to narrow down their possible choices. I find the game gives the feel of a WWI air duel but plays like an abstract game with a tiny bit of luck (the random numbers generated for damage when you shoot at another aircraft).
Here's a link to the results of a recent 3 vs 3 game of Blue Max where I was lucky enough to shoot down all three of my opponents. I was particularly happy with result because a new player on my side decided to leave the game on turn 5 which left myself and my other wingman vulnerable at 2 vs 3 of the enemy.
Here's another computer-generated image of a WWI aircraft by Mark Miller (all images property of and copyright by Mark Miller 2001-2006). This one has the colour scheme and markings of an actual Albatros DV flown by Vfw Otto Konnecke of Jasta 5 in 1917.
