As an update the review embargo has lifted, early signs look pretty good with averaging around 7-8 out of 10. The main reviews seem to be saying its quality over quantity with the main game taking between 10-15 hours but it does have multiple endings so may need a few playthroughs to completely see everything. Boss battles look pretty epic with multiple phase fights. The combat looks excellent with some comparing it to Sekiro (which has me sold).
The upgrades, plague weapons, potions and talents all look to be pretty deep. You can respec for no cost at any time to try out different styles (hallelujah).
For a budget game this looks really good - I can't wait to play it on Thursday.
