Play more games for less
Wait for sales. Steam and GOG run big discounts several times a year, and wishlists tell you when a game drops in price.
Claim free games when they appear. Epic gives away a title every week and GOG runs occasional giveaways.
Try free-to-play and open-source games first. Many have hundreds of hours of content at no cost.
Check the refund policy of the store before you buy. Steam, GOG and Epic all offer refunds under set conditions.
