I suppose it would depend on the type of game, but I don't think I like
this too much. The first immediate problem I have is the hacking thing -
looking at what happened with Diablo, my faith in any sort of encryption
is pretty low. The solution, it seems to me, is to have a central server
which approves any and all events that are to transpire before any other
clients except the initiating one recieve it.
Secondly, I don't like the idea of the complexity of the game being limited
by the client user's computing power. UO suffers from this slightly; a friend
of mine found UO almost unplayable despite an excellent connection (cable
modem) because his one meg, unaccelerated video card made his screen updates so
slow that he couldn't keep up with characters he was trying to follow. (I
recently gave him a Diamond Viper I had sitting around to get him to shut
up about it.) In a related note, I'd like to be able to devote the user's
computer power 100% to the actual display of the data - keeping a nice high
framerate and response time. If I want to make the game more complicated
on the server end, no problem - plug a few more processors or some more RAM
into our server machine. (Or, do an ultra-distributed server - a single
firewall machine running an 'uncrashable' connection manager, and a potentially
infinite number of server machines connected by ultra-high-speed optic cable,
with the connection manager delegating out process handling by checkup
load averages on the various servers.)
