^^No.Infact no such thing.There was a little fps problem in the leon level as i have mentioned before but its not that worse.Moreover i didnt encountered any bugs till now.
Anyways update:- yesterday only i finished all the three levels and completed the last jake level in co-op with a random guy(who joined in the middle).
.Now here is the big surprise which i got.Amazingly visually jake's level looks awesome as compared to other three levels.I can pretty much tell that at certain points it seemed like an exclusive title.Yes quite close to uc2 type quality!Hope they improve more in the final version.
As far as i am concerned not only the jakes level impressed me visually but gameplay wise also it is superior than other two.Yes i mean it jake is surely a character you would love to play with.He is agile,good with hand to hand combat, stylish and yeah smart. Kind of dante type you can say.
even his weapons are interesting.
Chris's level was really boring when compared to all the three.
Let me make it a bit simple.
Overall :- Jake>Leon>chris
I believe that capcom tried hard to make this RE version live up to its name.But it seems they got confused.Involving six characters was really not necessary until and unless you want to focus mainly on co-op.
