That’s what I’ve been saying all the time on previous forum, so much even I got fed up. Back when H3 was still faraway and everybody was playing H2, I was talking about these advantages of H2016 over H2:
1 - much more Escalations
2 - Proffesional mode is much harder than Master mode in H2 (enemies kill you easier, they are more alert etc) so it’s more fun to play hide and seek
3 - You can go and replay all the challenges in Professional level (challenges solved in Normal level don’t count)
There are some more pluses, but I forgot for the moment…
Of course, H2 has its own advantages, but most people were talking just about this issue, not the other way around.
