Why are you talking about problems with hardware... That's not about difficulty. Sure the screen flicker was a problem but not a great issue when you had a multisync monitor and worked in certain resolutions. The battery is a fact of life for all similar types of components. But not difficult...
Difficult for me, which on the Amiga usually means challenging, was setting up my home network on the A1200 using Samba and writing smb files and finally getting the machine to be seen by all flavours of PC taking into account password challenges and the like. Sounds easy but seriously was quite a challenge and I have to thank the good people of the Samba user group for all that help. Works without fault now.
Not sure I found anything on the Amiga really difficult. Some things stretch the limitations of the hardware, but that's not the computers fault.
The fun parts mostly involved scripts for your own tools, coding buttons in DOpus to undertake applications, defining icons to do certain tasks, AMOS - wonderful AMOS and AWNpipe all of which I gotta say still are more fun than anything on the PC. The list is pretty endless. Difficult only to start with but very enjoyable to master.
As to games... MicroMachines... Dunno why. I just couldn't keep the things on the table.
