Last year's winner has returned.
T.o.M.E. 4 has fended off commercial roguelikes (Dungeons of Dredmor), previous winners (Dungeon Crawl: Stone Soup) and new entrants (JADE) to win roguelike of the year for the second consecutive year, becoming at the same time the first roguelike to win more than once. Congratulations to DarkGod and his team for making such a great game and the T.o.M.E. 4 community for rallying around it.
With an incredible number of releases this year, it now features a beautiful tile set designed by Shockbolt, one of the most advanced user interfaces of any roguelike and a friendly community welcoming to new players.
Roguelike Radio will be featuring T.o.M.E. 4 for the first episode in 2012.
