What is the hardest thing about the game?

[EAF331 Starfire]

Seing a repeat of IL-2 series
2001:
IL-2 Sturmovik -> I gave up due to bugs

2003:
IL-2 Forgotten Battles: Gold Pack
-> I was affraid to buy due to my experiance with Sturmovik

2004
IL-2 Sturmovik Forgotten Battles Ace Expansion Pack
-> I was affraid to buy due to my experiance with Sturmovik

2004
IL-2 Pacific Fighters
-> Bought it (as a bargain) and got interested again but not enough to go online or buy the successors

2006:
Ultimate Flight Collection
-> I was still affraid to buy due to my experiance with Sturmovik

2007:
IL-2 1946
-> The same friend who I wanted to fly IL-2 Sturmovik with came and said it was worth buying. I had become mature.

This took 6 years

Will it take another six years and 4+ expansions?
