So, you bought a game on Steam, hyped yourself up, and... it's just not your cup of tea. Don't panic! Steam has a pretty straightforward refund policy. Most purchases can be refunded within 14 days of purchase and if you've played the game for less than two hours.
Here's the gist: Head to Steam Support (help.steampowered.com), log in, and find the game you want to refund under 'Purchases'. Click on it and choose 'I would like a refund'. Select your reason for the refund and choose how you'd like to receive your refund (usually back to your Steam Wallet or your original payment method).
Steam will then review your request. While they're generally good about refunds that meet their criteria, they can deny requests if they suspect abuse of the system. So, be honest! Good luck getting your money back and finding a game you truly love!
