Also keep in mind that orchestration and proper sample use is key. Listen to Final Fantasy Tactics and remind yourself that you're listening to what amounts to a MIDI sequence through a very basic soundfont from the mid 90s. You can spend $100,000 on sample libraries but if you can't orchestrate a simple MIDI file well then you're wasting money. Also I'm just gonna come out and give you some good advice that's kind of scummy but consider pirating a huge sample library to try it out and learn it, then buy it. (And I do mean BUY it because pirated versions are almost never up to date, and even then companies will release very buggy versions of their libraries as version 1, knowing that they'll be pirated like crazy and then shortly afterwards send a fixed updated version to the actual customers via email).
So yeah, use whatever means you have to obtain a copy of LASS2 and learn it, it'll give you a basic understanding of working with legatos, crossfades and divisi.
