I dont really understand why developers just love puzzles and stuff...Tons of time spent on developing and implementing on things that pretty much no one appreciate (if we wanted to play some puzzle games we would do that instead of playing this game). In my eyes its like adding a tetris between rounds in Mortal Kombat, many people will just lose on purpose just to continue playing MK or just skip if that was an option.
This game is an example that it doesn't matter if 1 or 2 aspects of the game are near perfect, they got the overall style of the game right, a few aspects they nailed it,
and then Fucked Everything Up with an amazing lack of direction of the project and lack of leadership when it comes to gameplay. What kind of a dev team decides that it is acceptable to force players to re-run the marathon from start to finish every time they update? Retarded/Scam.
If you are going to make new content that needs to be played from beginning, then stop being a retard/(SCAMMER) and supply players with save game points where the new content pops up.
They are either retarded on gameplay or they are doing it on purpose to fuck with the customers, and I see no reason not to give both theories the same probability, they are probably doing shit on purpose to drain energy from people.
They are trying to make YOU, the customer, think it is YOUR fault you can't see the new content.
They're going to keep going this way thanks to the simps.
TL, DR: they are playing mindgames and mental gymnastics to be able to keep working as little as possible while making you blame yourself for not seeing the new content.
