Pros:

-Good old school L4D 1 style (the one and unique)

Cons:

-Too long chapters (can be splitted in two)
-Lack of medkits
-Lack of weapons and ammo
-hordes, specials, hordes, specials ...

-Way too hard due to these four points.

Conclusion:

The left 4 dead 1 feeling i search (so rare these times) but ruined by lack of a lot of things.
Split levels, add more items, reduce a little hordes and specials and it'll be perfect...
I gave up playing at map 4, stuck with 2 wooden crates...

Pros:

-no skies bugs (like previous day mod)

-many l4d2 props (jimmy cars, dead l4d2 survs, chainsaw, axes, graphittis, mrider bus...)

-l4d 2 intro music

-blocked redundant ways

-Silent hill 3d movie 

Cons:

-Too many witches, that's just too hard.

Conclusion:

Ok, in the new version wall poster textures are fixed, i finally saw the l4d2 special infected on the floor (great idea) but please reduce the witches number. 3 or 4 that's fun, 20 that's really annoying.
Also in map3 i read on the wall MANY WITCHES IN THE HOSPITAL, THIS WILL HELP, but nothing on table down arrows. Put an auto shotgun.
Not so far from a perfect mod. Keep the good job.

Pros:

-n64 colors and levels, high fidelity

-"for england james" graffity

Cons:

-some pink and black tv's

-runway part too short

-no tanks on levels 1 and 2

-tanks by pairs in finale

-no musics (at least l4d sounds would be nice)

Conclusion:

suggestions :

- in LIBRARY the window where james bond jump to escape in n64 game is covered by sheets of papers. make a window with an exterior with army vehicles (like st petersburg tank). 
- in CRADLE place a medkit where there was an armor in original n64 game and try to place the escape chopper at the escape ladder of the movie (For England James? NO, FOR ME)

Nice work ! Keep the good work.

Pros:

-totally different game from l4d1 version ! : many more props, many more textures, some new stages parts.

-panic events (explosions, incendiary, alarms)
-so good tanks in footbal suits !!!!

Cons:

-really really nothing, no bugs, no annoying difficulty, no lags....

Conclusion:

Oh my god ! The PERFECT l4d2 conversion giving a MASTER l4d mod the GOD l4d2 status! REALLY. Keep up the good work, one of the best mod ever played.
That new orleans feel, nore action, end cinematic we'll remember long time... Oh can't find other words to describe that masterpiece !!! Did the developper works for Valve ?

Pros:

-5 maps extended (mirrored)

Cons:

-2 CEDA posters pink and black (levels 1 and 4)

-many invisible containers (levels 2 and 3)

-when u die in finale and retry, fuel for generator is gone in saferoom

-no CRASH COURSE MODIFIED title in credits (again pink and black)

Conclusion:

It's a pleasure to play CRASH COURSE free and extended in l4d2, seems better than l4d1 too short original campaign.
But i listed little bugs i think you can fix easily many months after release of v4. You made progress in modding no ? please update and make me happy because i play frequently that version.
