Looking to dig into some of the best computer RPGs ever made? You won’t find a better opportunity than the RPG Masters Humble Bundle. Right now, you can pick up a collection of eight classic and contemporary CRPGs, along with a fat stack of add-ons, for just $35 at Humble — a savings of 90% for a collection of games that normally costs $346. But you’ll have to act soon, as this deal ends Wednesday, Sept. 4 at 9 p.m. EDT/6 p.m. PDT.

Finally, while it isn’t a true RPG, you’ll also get an 85% off coupon to purchase the co-op roguelike MythForce from Steam, giving you the chance to add this Saturday morning-flavored hack-and-slash to your library for just $4.50.

Humble Bundle always sends a portion of each sale to benefit a nonprofit — in this case, your purchase will support the Girls Make Games Scholarship Fund, which works to create spaces for girls to explore the world of video games and close the gender gap in game development. Just remember you can always use the “Adjust Donation” drop-down menu to fine-tune how much goes to the publisher, the charity, or Humble.
