Well all the Souls series and even Bloodborne have a on on-line tutorial.which actually does explain the controls.

The thing with Action RPG's and make no mistake BB and the Souls series are ARPG's that take many 10's of hours to complete (speed runs exempted) . With this in mind the player of these games has to invest the time to play them no matter what the difficulty. If they can't then maybe they should play a shorter and possibly easier game.

The BB and Souls games are difficult but they are fair and you can always find the appropriate weapon and tools to go up against any creature or enemy and win. In the worst case you can even level up. I personally found that levelling up in Demon's Souls and Bloodborne was essential for me although in Dark Souls I normally level to 15 and can pretty well complete the game at that level although there some very skilful players who can do better then that.

Personally I refuse to use the difficulty slider if one exists once I have selected a difficulty level. To me changing the difficulty on the fly just because you find an enemy a little too hard is IMHO similar to cheating but then again if it does not affect me then I don't really care since the person who is doing that is only cheating themselves although I am quite sure they tell themselves this is a valid thing to do since they can't do that in real life.

When I start a game that has a difficulty settings I predominately choose "normal" or it's equivalent but if I find that is too easy for me I restart on a higher difficulty . I actually did this on The Witcher 3 and eventually restarted on "Death March" since this difficulty allowed me to appreciate the game mechanics whereas the other difficulties did not and like I have said before I refuse to drop down the difficulty by slider just because a particular enemy is proving difficult, you can always come back after you have got new weapons and armour or levelled up. Of course some people cannot see the relational behind what I just said and that is fine by me, their loss not mine.

Personally I do enjoy a challenge in a game however I don't classify myself as a highly skilled gamer and I know when the difficulty level of a game is too high for me to play and just don't play it nor do I bitch about it either. Bloodborne and the Souls games do present a challenge which actually test my skill and perseverance and after you beat a particularly difficult boss the elation is great and the virtual workout can be likened to a 100m dash.
