For me, when finally having time to get back into flight simulations,
1) All ready had a purchased IL-2 1946 DVD (actually have all version, including BOS)
2) IL-2 runs beautifully on my machine, BOS won't, & forget DCS world, not even gonna try (until have built a new machine) .
3) No other title even comes close to the scope and content of IL-2 1946 4.12, even more so w/ HSFX
So, IL-2 is going to be on my hard drive for a long while (at least two more weeks).
