it's similar to PR. let me list some random shit:
0. soundtrack is dank
1. ww2 focus
2. people die in a few shots
3. theres bullet drop but it's a bit negligible
4. realistic maps
5. realistic factions from what I know
6. dedicated dev team
7.more realistic and team focused than BF2/2142, but to a more of a casual level than PR. it is basically the inbetween of BF2 > FH2 < PR in that order, BF2 being the most arcade PR being the most realistic.
also, soundtrack is dank.
worth a try, I used to play it a ton back in the day(before PR), tried it recently and didn't like it. that's just me though. I only do not like it because i'd prefer something like ARMA 3 WW2 or Day of Infamy, and if looking for nostalgia i'd go to BF2142/BF2, also I don't know anyone who plays it so that's also another
just give it a try, it is free after all and installation(edit: as in I was playing by 8 min) took me maybe 8 min, less if you know what you're doing
edit2: also this is general discussion for PR, probably should've posted this in FH2(edit3: i meant off topic discussions) with a title like "Is FH2 like PR" to not conflict with the already-ongoing FH2 disucsison
