Free software for simulating 桌上, 桌面 RPGs online. Great for gamers who are unable to gather with others on a regular basis due to time 或者 distance constraints.
The online true 随意 number service. Forms allow 你 to easily and quickly generate a 随意 number 或者 a series of 随意 numbers in virtually any range. (2d8+22) + (3d30-5), anyone?
Pretty interesting attempt to preserve the best aspects of pen and paper rpgs within a software interface. Haven't personally tried it out, but it looks promising.
