depends on where the mod looks for the right lines od code to be used from the "original" game.
if the mod does not look in any of the files the usual "no-cd-patches" change, then yes, MWLL will work with it.
if the mod does look into the files changed by these "no-cd-patches", then it depends on how much was changed.
if anything was changed that the mod needs really hardcore like . . then no, it won't work at all.
if they wanted to be sure that their mod works, they could include the files that are changed by these "no-cd-patches" and change them back to the state they need to be in for the mod to propperly work. and now you have an version of crysis installed, that is not cracked and will need an "original" disc to play with. and if you apply the "no-cd-patch" again, it won't work with MWLL, and depending on WHAT the Mod DOES change, the "patched" version of crysis might not work either, no matter if you try to play vanilla or mod.
Also, most stuff i pirate are things i can not get a hold of using money.
Things like ULYSSES31, Bionic Six, Cadillacs and Dinosaurs and other such old goldies ^^ (Still looking for Dino-Riders and Silverhawks by the way^^)
Most of the time, buying is faster and easier than downloading and trying to get it to run . .
ok, DOW2 gave the RIPPED Version a Run for the money, due to steam bitching around . .
But usually: go to store, give someone money, take product, apply at home at leisure, is easier and faster than:
wait for it to be released . . fapping FIND the release . . download several gigs with speeds between 1 and 100k/sek . .
then try to figure out how to get it to run . . then have it be automatically patched so the included "no-cd-patch" does not work anymore . .
then try to get a new "no-cd-patch" for the legitimately patched version and getting that one to run again . . then not being able to play multiplayer in most cases(though i usually don't play that anyway, so not such a big thing for me) . . and then having to redo the patching each time the product gets another update, having to deal with incompatibility issues with 3rd party stuff like mods and addons and such things . .
but lately, with being limited to installing the game to only 3 computers . . or only 3 times PERIOD . . i usually use a version i got off some P2P network, that is allready cracked and does run and can be isntalled how ever often and where the fapp i please . . i might stilly buy it if i wanna multiplayer or something like that, or if i just really like the game or the whatever about the product . .
I don't know how many illegaly downloaded versions of MW4Mercs i have loitering around . . i know where my bought CD-Keys are, most of the time, but i don't know where the discs are.
so i just re-download the game and install the english version using my bought german keys . . especially, since the bought Mercs Discs all seem to produce the same error again and again over time . .
