I must say their regional pricing, at least for PL, is very tempting.
Hades 19,99 EUR -> 49,00 PLN (on steam it would be 71,99 by default)
Hello Neighbor Hide and Seek 29,99 EUR -> 79,00 PLN (107,99 per steam default conversion)
So the difference is significant, but I'll wait to see how deep the discounts go, I buy most of the games at -8090% anyway. ;-)
Now if epic store generated keys that the devs could put into bundles, things would become really interesting.
