That could be very interesting to go in-depth on. Maybe focus on graphical innovations throughout the history of video games and how they've changed the way games look? I'll need to make a note of that and think about it. 

It would require a lot of research. If there is a lot of information to write on, maybe have each article focus on a single decade or a single generation. 

The rise and fall of a specific game genre maybe?

Don't want the code, raises conflict of interest issues anywho. But I'll answer anyway.

My favourite Soulslike is Dark Souls 3, with The Surge a strong second. I completed From's games all out of order, but one straight after the other (Bloodborne then Dark Souls 2, then 3, then 1 Remastered), and 3 was definitely the strongest for me. By that stage they'd nailed the formula and the visuals  (and atmosphere) were on another level to 1 and 2.

The Surge was the game that got me to give the genre another go. I'd originally bought Dark Souls 2 on PC when it launched and found it to be completely inaccessible. The controls were totally messed up and the lack of structure and explanation for how everything worked meant I didn't have a clue where to go next once I reached to main hub or what to do with my character, and so I predictably ended up hitting a brick wall of difficulty for a newcomer. But I gave the genre a second chance with The Surge, which was more accessible and structured at the start. Loved it, eventually gave Dark Souls 2 another shot, having banked up some experience with the genre, and that time it all clicked. Have devoured every Soulslike that looks half good ever since. Will be getting Hellpoint too.

Does darksiders 3 count? if so its mainly because of the keepers of the void DLC that properly combined combat and platformpuzzles.
aside from being hard in general on the higher difficulties, bonus points for the badass female lead
