That's a strange reasoning. Perhaps you meant "..for a chat-based
multi-user game" ? Otherwise, it's an excellent platform (as
evidenced by the considerable number of people on this list who have
tried using it, albeit usually experimentally IIRC).

JWS is currently NOT a functioning technology. It is *broken*. My
current advice is do NOT use it except in addition to other
distribution channels, and expect to have to support people. Most of
the bugs I've seen in JWS (latest version) are workaroundable (but
see next para...), but you have to tell your user what to do - there
are no code-based solutions AFIAA. Wait a few versions, and it
should be fine. Bear in mind that when JWS doesn't work, it may be
difficult to get a message to the user to tell them what to do to
make it work!

Also, on many win32 desktops, JWS works extremely badly; I've been
given a list of suggested workarounds, and haven't fully tested them
on my example broken machines. I do know that the win32 problems are
quite common, whereas on nix platforms JWS seems to work out of the
box for *everybody*.

All of which is a pity, since other than that JWS is pretty darn
good.

downloadable + applet is generally not a sensible combination.
downloadable + application is identical, except the programmer has
to jump through fewer hoops. The client-side download is also easier
to run and maintain (you just double-click it! No need to bring up a
webpage etc - some users WILL accidentally delete the JAR file if
they think they just need the saved webpage, and vice versa, thereby
breaking it :( ).

Visit javagaming.org - Sun's (semi) official site for java game
developers - and the forums there for in-depth discussions on pros
and cons of different java-based game distribution
techniques. There's quite a lot covered in the forums, so you may
need to dig/search a little.
