First off, your music sounds great! You've clearly got talent and know what you're doing!
Secondly, game music is quite different from linear music due to the interactive aspects of gaming. Study up on middleware and how game engines work.
Thirdly, you mention looking for a "huge" freelance job. But without previous game credits, it's going to be harder to land a huge game job out of the gate. Not impossible, just harder. Perhaps you need to adjust your scope.
Finally, consider the type of music you're offering to game clients. Sometimes folks may not want the style of music you're offering. Much of your stuff sounds great for trailers and TV spots but is it good for an in-game experience? You may need to re-evaluate what you're offering and what most game clients seem to want. (With the caveat that game projects and needs can vary greatly.)
Listening to the three tracks you've posted - they all sound great. But they're all the same basic genre, intensity and vibe. Some clients may want to see how versatile you can be in your writing. Can you create light-hearted, whimsical tracks? Can you create simple, ambient tracks? You can obviously create huge, epic, sweeping tracks. Can you write in ethnic styles? Can you interweave core themes across a whole soundtrack and have it be cohesive?
I'm not trying to talk down to you - hopefully it doesn't come off that way. You're clearly very talented and do great work. But when changing markets you always need to consider the new needs, trends and tech limitations of that new market. I hope that helps!
