From a technical point of view, I'd rather choose BREW over J2ME. There are many caveats with J2ME that will make your game run very slowly. At least take a look at the custom vendor specific Java game APIs, which would provide several performance and design advantages (e.g. pre-made, clean game specific libaries).

BREW is slightly superior technically. All of the handsets I've seen to date didn't really outperform the J2ME phones, but you have access to a lot of lower level stuff that the sandbox model in J2ME won't let you. The biggest problem is that developing for BREW costs money, whereas with J2ME all the tools are completely free.

shmoove

Im dont really know anything about publishing, i was gonna just make a demo of some sorta, see how popular it is, then see if anyone will support it. none of my friends have 3G, so i wont be doing much testing on that network, besides, when/if i complete it itll be sumwhere in 2005 anyway.

BREW sounds great and all but i dont think many phones have it, plus ill have to learn a new langauge (plus i got no munni :D ).

ive seen tiled games working smoothly on j2me phones, so i know java is more than capable of achieving what i want. although i probably need 3rd party APIs later, atm id rather get the experience out of making it myself.

oh well, now i just gotta finish exams and i can start....
