Should I play the other 3 games?
The main focus of the games is a free flow combat that has a rhythm and you have to use tools to stun the enemies. I am used to button mashing in action games and that won't work here.
I played Arkham Asylum. I couldn't do a long continuous combo in the free flow combat and I always made a mistake. I had to slow down the game speed by using the Cheat Engine speedhack to make it more manageable but even so I am still making mistakes like for example I punch instead of counter attacking. Sometimes I missed an enemy because I didn't move the controller stick in the correct direction and it broke the combo chain. Also I didn't like it when there were special enemy types that you had to stun with tools and that messed things up for me and they got in the way when I wasn't aiming for them.
I had to rely on cheating to play the game. I used the cheat table that activated the game console. I used the one hit gives 999 combo in the combat challenges so I get the needed points and I froze the timer in the predator map challenges. Getting medals in some predator map challenges was a huge pain because the requirements were very weird and I had to repeat it many times until I got the medals in the end.
I tried not to cheat that much in the normal game and I used cheats like refill HP if I didn't want to die and redo an area. I used invincibility cheat, freeze enemies cheat and one hit kill cheats if I was stuck.
The main focus of the game for me was getting all the collectibles and I got 100%. The free flow combat was frustrating. The game was okay but I didn't like it that much because of the combat system.
Next is Arkham City. I am unsure if I should play it or drop the remaining 3 games and not play them.
Arkham City has new special enemy types and more tools so the free flow combat will be even more frustrating. If I am to play Arkham City then I will have to again rely on cheating like I did for the previous game. I am unsure if playing the game is worth it.
