Every year, there’s a challenge to make a fully-functioning, playable roguelike game in seven days. For more information about this year’s Seven-Day Roguelike (7DRL) Challenge, you can check out “7DRL Contest 2011” at RogueBasin. There’s also a Facebook event for participants!
The 7DRL Contest isn’t organisationally related to Ludum Dare in any way, but seeing as there are many people here who are willing to
subject themselves to suffering make games within absurd time limits, I thought it might be worth the advertisement.
