Pros:

-nostalgia maps are always great
-sometimes i look at places that i remember that scared the crap out of me in RE2.
-nice references to KENDO and alleys and stuff outside
-lots and LOTs of details to original
-wow factor is huge in this map

Cons:

-lacks the keys and number of puzzles that the original had
-confusing with the outside areas constructed as well
-objectives not too clear
-the way i played RE2 interfered with where i wanted to go and where i needed to go
-some parts of the map not included like library
-biggest problem was finale panic event, i walked all the way to the other jail cell and not to the dog kennel room, and then got pwned by tanks as i realized i took a wrong turn. 

Conclusion:

short, but sweet. i actually noclipped through to some areas i thought i could go in. the police chief's office secret door actually has a hidden passageway! are you thinking of including this in a multi map campaign!?

Pros:

-would be great for VS maps
-huge maps (pro and con)
-the ship level panic was hella tense
-navigation was clear and i did not get lost (much)

Cons:

-too big for a run through coop mode
-too big to contain little details that make you go 'wow'
-not too coherent to tie in the maps

Conclusion:

some good parts, but also some bad parts. the map was big for its own sake, and not good on flow or pacing.

Pros:

-it's not bad, contains some details in a map that can be overlooked through first run of map
-the first map was well done, and then it felt that the author got bored halfway through.
-finale was good, although confusing in where to go.

Cons:

-toronto is one of the most boring cities ever. (according to this map)
-rough edges in tower
-how do i tell that this map was in toronto and not some American city?
-not very realistic or believable map
-confusing to navigate at some parts, elevators and switches do weird stuff.

Conclusion:

This is a solid map that needs a tune-up to reach a 'great' status.

Pros:

-Captured the scariness totally
-common running out of fog scared the crap out of me
-solid gameplay that deviates from the l4d formula
-scavenging hunt is fun for weapons, ammo, items, etc.
-later levels were scary as hell (in motel etc)

Cons:

-dark hellside maps(in hospital) were tedious and textures were boring
-ERROR signs flashing (in beta stages)
-finale flythrough was interesting, but still got some ERRORS there too
-not finished yet

Conclusion:

PLEASE for the LOVE OF GOD FINISH THE MAP!
