It doesn't take many technical steps to get good-quality video game scores.  You just need a MIDI-keyboard with at least one octave ( two octaves would be better though ), a DAW with a library of half-decent samples ( Logic or Reason ), and some half-decent headphones.   It shouldn't run you more than $400 and you'll be set for a long time to come.  It's all lightweight and easy to transport, too. Focusing on having a good setup isn't bad but composing constantly is the real key.

For DAWS, if you're looking more toward electronica, Logic has some good sounds.  It's interface is very simple too.  It has a few good orchestra samples but the choices are limited.  I use Reason more than Logic, maybe just because it's the one I got deep into first, but it has many string and orchestra samples that fit with fantasy games, plus it also has many electronic sounds that can be tweaked to no end, plus it's cheaper.  It's a harder interface but you get used to it with the time spent.  Any DAW you get fluent in, just like any instrument you get fluent in, will translate into other DAWs, the most important thing is putting in the time.   I compose almost everything in Guitar Pro 5 with MIDI sounds before I export it to a DAW, it's just the way I've do it the way I done it, brain tells me it's old and I need to get with the times but brain's wrong.  Get fluid with the language of your DAW and you're set.
