Not unless:
6. No more retardedly nigh-impossible Achievements/Trophies linked to acquiring Leaderboards noms.
I'm not much of an achievement hunter, myself. Granted, I am horrible about being a completionist, so if there's a piece of equipment/costume/bonus character or whatever in a game, I go out of my way to unlock it. After I got done leveling up all of my factions to 99, got every character part, and unlocked every weapon and grenade all that remained were acquiring Noms de Guerre. Having one that's almost impossible to get due to the fact a large number of people use glitches to get unbeatable times (unless you somehow luck out and cheat better than they did) annoys me to no end.
Especially since the community, back when we actually had one for this game, tried to bring it to Capcom's attention repeatedly in hopes of getting some sort of leaderboard updates so everyone would get a fair chance. No dice.
7. Capcom actually bothered to do anything about bugs/glitches that may be in the Colonies edition, and stays on top of communicating with its fan-base.
After how this community, game, and franchise has been abandoned by its creators, I'm incredibly wary to drop any more money into the Lost Planet series. I love'em to death, don't get me wrong. But considering there's practically a communications black-out between us and Capcom, on a Capcom-sponsored forum it should raise some red flags. When the PS3/360 players pointed out glitches and bugs in the game, they were never resolved. When the PC players were stuck with a broken-ass release (the whole GFWL/Steam problem), they barely got so much as a confirmation of "Hey, we're working on it." and were left in the dark for a while before the game was "fixed". And I say "fixed" very loosely because there's still a plague of people finding new and exciting ways to cheat their **** off in multiplayer using hacks, which Capcom has done nothing about.
If I'm going to actually buy anything else LP-related, Capcom's got a lot of apologizing to do towards its fans for how they handled (or, namely, didn't handle) LP2.
8. Plasma Cannon SP gets a nerf, we get to shoot homing rockets out of the air again, and the splash-damage for the regular Rocket Launcher gets put back to how it was originally.
I'm sick of bunny-hopping Plasma Cannon SPs thermal-locked with Injection Gun II. I hate that something as lame as a homing rocket can't be countered by shooting it out of the air, and instead I have to go try to find cover or stop whatever it is I'm doing and time my roll to get out of being killed. Also, I hate that a classic weapon like the original Rocket Launcher barely has any splash damage compared to how it used to be, since having to practically hit somebody dead-on with it makes it borderline useless since LP2 has the Handcannon.
The changes to the weapons that were applied with the patch made multiplayer kind of suck.
9. REGULARLY UPDATED/RESET LEADERBOARDS.
10. Expanded Campaign chapters.
Campaign was the real blood-and-guts of the game, but it was a little too short. I don't care if the story was kind of lacking, or that my character's mouth didn't move in cut-scenes, or whatever the hell else people whined about. Just more campaign that I can play co-op with people. The more there is to do in campaign, the less I have to deal with the game's annoying-as-hell versus modes.
11. No player-rank BS.
The whole player-rank system was retarded. And I don't mean that figuratively. I mean the system itself, which was coded and implemented, the one that determines your player-rank promotions/demotions, has Down's Syndrome. Whatever black magic/voodoo it runs on does not work very well. The only bragging rights you actually get for achieving Overlord is the right to brag of having the saint-like patience it takes to get it, in which you could've just used that time and energy to find something better to play.
12. More character models.
Sorry, but I like playing dress-up. :P Half the fun of the game's replayability was the fact you could unlock more stuff from the slot-machines and get more weapons, but a lot of the fun was getting some new character part to put on your guy.
13. Regularly released DLC.
The DLC for this game has a history of pure sucktitude. Map Packs were great, but nobody ever played them because I think only like, twelve people bought them, so that didn't pan out too well. The Boss Rush-Mode DLC? Awful. It was missing half of the bosses and the difficulty level couldn't be adjusted to actually make it challenging. It was good for like, 1 play-through, but you got a funny costume for it. After the novelty of laughing at "HEY DUDE! TRY TO ACTIVATE ME! LOLOLOLOLOL!" shenanigans with the Post-Modern skin, it dawns on you that you've essentially just spent like, $12 on a character model.
I'd be more keen on buying the Colonies edition if I knew I had more than some half-assed Boss Rush and map-packs I never get to play to look forward to in terms of DLC.
Those are what would coerce me into buying an LP2:C edition. Yes, I'm aware that it's a long list that's essentially a "Capcom, ya dun goofed!" complaints. But if they weren't legitimate complaints, this forum and the GameFAQs forums would have more than 12 people collectively posting in them, don't you think?
