TinyTIM is the world's oldest MUSH (Multi-User Shared Hallucination), and as such, is full of people pretending they have exciting lives that aren't wasted sitting in front of a flickery computer screen, sobbing as they masturbate to lengthy room descriptions and lame attempts at roleplaying.
From the TinyTIM support website (What is TinyTIM, Anyway?):
—clever lads, they are
Wow. A cow? That's really wacky.
How to play
- Telnet to yay.tim.org 5440
- Create a fursona
- Pretend to be an exciting and interesting person (or elf or dragon or hippo or whatever)
- Come to the realisation that the time spent on TinyTIM could have been better spent actually BECOMING an exciting and interesting person
- Slit wrists
Is it really text-based?
No. TinyTIM actually has a rich 3D-graphical environment, with each object, room and character rendered in real time. However, when you begin the game, you only have access to the text version. The graphics must be unlocked, either by completing certain hidden quests, or by making a donation of $100 or more to the MUSH's founders.
