For a short period of time a pathway has opened to get into the realms of certain traditional roguelikes for discounted price.
Steam offers Awesome Traditional Roguelikes bundle - with UnReal World naturally included - until 13th of August. We, and all the games included, also offer individual Daily Deals so you can decide whether you wish to pick a good fistful roguelikes, or just a selected one.
