Is it worth entering the Holy Temple in Dark Devotion? Yes, I think it is, but you do need to know what you are in for. Put another way, I can definitely recommend Dark Devotion because I did come to have fun playing. It took me a bit to get there, and that may prove to be the same for you too. It is not an easy game, it is definitely challenging, but it does feel like your investment of time, improving your skills and your character, is rewarded with the victories you achieve over the enemies and bosses you encounter. You do need to expect to make that investment though, and be willing to make the investment too. Recommended, but expect some frustration and maybe some degree of head-smashing.
