@jfan813 Technically, you could install Windows on your Mac. There are a couple different ways, but Bootcamp is much better for gaming than Parallels: the drivers are better, and the hardware doesn't have to support two OSs at the same time. The idea is that you partition your hard drive, install Windows on one side, and boot into Windows when you want to play. How well it works will depend on the specs of your Mac, but it looks like Dragon Age: Origins isn't especially demanding. Here's Apple's main article on Bootcamp:

The main requirement is that you have enough storage to set aside for Windows without compromising the Mac side of the partition. Since the game requires 20 GB storage, 100 GB total for the Windows side should do it. But you can't resize the partition unless you wipe it and start over (wipe the Windows side, that is), so you'll want to make sure you have enough space.
If you'd like to go this route, feel free to ask more questions. I Bootcamped my MacBook Pro almost two years ago, and it was surprisingly simple. But it's a bit harder on older Macs, I think most models made before 2015.
If you'd rather skip the whole process and get a refund, that's also a reasonable approach.
