Right now I’m basically playing Beyond All Reason almost every evening. It’s a game in the Total Annihilation “tree” of games. A massive scale RTS. I previously played Supreme Commander and Planetary Annihilation, both of which are also inspired by Total Annihilation, but I have to say that BAR is really better than both of them. I almost can’t believe it’s an open source game. It’s still in alpha, but it’s been way more stable than most AAA games I’ve been playing recently.
