I think that Dark Souls series are interesting example of RPG with strong strategic and tactic influences. It's not the same "strategic" as in RTS games, but, with no doubt, playing in Dark Souls requires very tactical approach from the Player. Every fight in this game, even with easiest opponent, requires accurate planning and foresee the opponent movements. Dark Souls mechanics force players to tactical approach not only in fights, but also in exploring the Lore - risk and go further or go back to save bonfire and starts this hard section once again? So, for me, it's not very obvious to call Dark Souls a strategic game, but for sure this title demands strategic mind.
