Well, if you're going to have a MorphOS machine, there wouldn't be all that much need for getting the A1200 online as well, and these days it's not much use for web browsing anyway. Having said that though, a network and FTP can be quite useful for transferring files to and from other machines on your network.
As regards games, you'll probably find many of them won't work when run from WHDLoad without a memory expansion at least, since many games assume they have total control over the base machine. Keep an eye out on eBay and the classifieds sections on the various Amiga forums for ACA1230 and Blizzard 1230 boards - others might be worth a look as well...
