Discord across the hivemind synapses
Okay I am going to respond because you seem ready to talk maturely, plus I hate talk of emulators/compatibility issues/source ports etc, and all that sleep inducing crap which threatens to infect this thread (Doom thread ugh)
The disclaimer to this is that it is not a comparison to DK1 because I haven't played the game, and I would be quite prepared to enjoy it more than DK2 if I even get the chance to try it one day.
I don't understand why you brought up the DK2 creatures. A quick look over the DK1 creature list shows that not only are most the same, but they are all very typical unoriginal fantasy monster cliches (which I have no real problem with, especially given how well it fits into the whole fantasy-caricature style). I am always more a fan of more bestial creatures than humanoid ones. Expectations are hard to live up to, sure, but it isn't a very appropriate argument in this case. Personally, I would have used more outrageous creatures too.
Cannons: extra traps. Are you complaining about having more traps to choose from?
Casinos were fun. They made the style IMO. One which I gather is more light hearted and childish than the predecessor but a distinct one nonetheless. Creatures going to gamble and drink in the casino (yes they all had animations.), even winning jackpots that sometimes wipe out your whole treasury? What's not to like? Yes, Disco inferno.
Heroes looking generic jrpg. That is the whole idea. It is fantasy caricature. They are meant to be ridiculous and sickeningly goodie-goodie. They are meant to make you want to roll boulders over them (how was DK different?).
The attention to detail was definitely in DK2. Creatures using different rooms, exploring, relaxing, having moods etc etc. All creatures had eating animations, I don't know why you mentioned it. Watch the creatures eat and do their thing, they have a lot of character and it is animated. Blood groups and secret levels I responded to already.
I would be interested to hear about what attention to detail was in DK1 that wasn't in DK2 though.
As for the over-world map and campaign, I have no complaints there. I don't know how DK did it but I was happy with DK2, given that it let you choose missions sometimes and gave a sense of progression etc. Could have been more difficult, yep.
Stuff about nowhere to build, no gold, I don;t know what that is all about; sounds like you sucked at the game or something. Bigger maps are always better and while some maps were big, others broke the monotony with pre-built enemy castles and such. Was fun for a change IMO
You are welcome to consider localisations in your evaluation of things within that version but unless we are comparing the same language version (and I did play the English one), it is rather pointless.
I encourage you to tell me about all the things that DK1 did differently or better, but stick to things which DK2 doesn't have or it isn't much of a comparison is it?
