the thing you have to keep in mind is this: FFH2 is no longer being worked on, it was developed over the course of years and is now in its "final" state. Elemental is brand spanking new with years of development ahead of it. Right now, FFH2 may be more stable on some systems, have deeper gameplay ect. ect. ect. but it got that way through developer commitment and community feedback and support. FFH2 is a great game, but its static. if there is something you don't like about it (and there are plenty of things not to like about it) then it isn't going to change. Elemental is just starting its journey, and I for one am excited to be along for the ride 
the best thing about FFH2 is that its races are unique, but then thats something that SD has said they want to do with Elemental. its something they accomplished fairly well with GalCiv2, and im sure they will get it done here, just takes time. FFH2 didn't hit the mod scene fully formed and bug free, it took years to get it to the level its final build is at.
ps: people need to stop saying FFH2 is free. its not. at some point to have to have bought or buy Civ + warlords + BTS. if you are like me and you bought them all new, then it cost something like $90 total. you can get it cheaper now, but its not free. stop saying it is.
