  Measured in their handshakes: MSSP

AresMUSH is the newest server in wide use aimed squarely at collaborative
roleplay, and it takes a different position from the TinyMUSH line it succeeds.
Where a PennMUSH game builds its scene system, its character sheets and its job
queue out of softcode written by whoever was around, Ares ships those as
features and expects a game's staff to configure rather than program them.

It comes with a web portal — character wikis, scene logs, forums and the game
itself, all reachable from a browser — which for a genre where people read the
logs afterwards is a substantial difference in kind rather than in degree.

Configuration is in YAML; extensions are Ruby plugins. There is no in-game
programming language for players, which is the trade: less rope, less
rope-related injury, and less of the improvisational building culture that the
MUSH line is named for.

WHAT IT LOOKS LIKE FROM OUTSIDE

No MSSP. It answers a pre-login WHO, and the answer is a per-player list rather
than a bare number, which our parser counts by structure. No telnet options were
negotiated on the game we measured.

If you are choosing between this and PennMUSH for a new roleplay game, the
question is roughly whether you want a system you configure or a system you
write.
