There are also ways to download DAWs for free but it pirating. If that doesn't bother you then that's another way to go.
Just use extreme caution here because if you end up producing music for any games and pirated software and you get caught - both you and any games using your material can be liable. I find it's best to just purchase things instead of pirating them. It's not worth the risk. If you're looking to just learn and experiment... it's less risky. Still not legal but less risky.
