Mad Max player wanted to try Batman-Arkham and it's sequels, answer me some questions. 1. I find Mad Max somewhat easy and casual, I manage to 100% it without much trouble. Is it the same with Batman-Arkham? 
2. How is Batman-Arkham's combat compared to Mad Max and Shadow or Mordor ?
3. To get a better feel, are there any particular order i need to play first ?
4. Are there any ridiculous challenges that will require insane amount of luck to complete ?
5. Is there any 'stronghold' I can build and upgrade ?
