I do understand the difference between console and PC, so I understand some games being unplayable on the keyboard, though making the camera work by using another set of directionals is one of the most ridiculous things I have ever seen, but since I know these games are made for gamepads, and I personally prefer gamepads, I really don't mind.
I do not mind graphics being slightly inferior, DW8 was fine for me, because mods makes PC games infinitely superior to any console (and modable DW8 was way better than the PS3 version that I already had), and considering the main graphical difference with the PS4 is not even just just the models, but lightning effects and stuff that some people hated, it is not really a big bother for those that are not "PC Master Race that demands everything to be better than their console counterparts", could we get a PS4 release? Sure, but it's really not necessary.
I believe japanese companies are still console focused, that's quite inconvenient, but a sad and unfortunate reality, and we all know that they have little experience on PC, even good ports like DB Xenoverse had problems with game mechanics using FPS ticks for effects, sure they were fixed eventually, but the fact is that expecting a perfect port from japanese companies is being quite unreal, and the number of japanese companies with great IPs deciding to port some of their main games to PC is awesome, so I think that it wouldn't be bad to welcome "not PS4 ports", as long as they are playable and have full content, or at least full of what people really want, and I'm not talking only about TecmoKoei, but others like Sega and BandaiNamco are also included on this list.
I would say it's fine that DW8Xtreme Legends did not had Multiplayer, the game is not multiplayer focused, sure it would be nice to have it to have some random fun possibility, but many players are fine without it, DW8Empires has the same PS3 graphics since they share DLC and stuff, so it was expected for it to keep the same engine, meanwhile, content is complete there too, except for multiplayer (No idea if PS version actually has multiplayer though, since Empires has different playstyle), but there are online resources, like downloading other people custom characters and custom campaigns on Steam, and DOA5LR has great graphics, the only big difference from the PS4 is the Soft Engine, which is really not necessary, and the only thing that sucks big are the lack of online, and those 2 new stages that are absent from the PC version because bullshit, the port is not the best, low FPS makes the game run in slowmotion, but it's playable on high settings for many more moderate specs, and mods can fix many graphical things, like bad textures. These games may not have been PS4, but they are not bad, and are fully playable.
Meanwhile, I really want to buy Bladestorm (and later Toukiden), and I was counting the days before its release, but the graphical problems and unstable FPS, even on lower settings is just not acceptable, specially for full PS4 price (instead of PS3 price). I'm waiting for a big discount (50~75%) like they already did with the DW8 games, unless they actually fix this bullshit and make the game fully playable, but I guess I shouldn't count much on it...
But of course, I could be called a fanboy... One that is really happy to not need to play them on PS systems anymore, that is not asking for 60fps or better graphics than PS4, just a fully playable and fun game. In short, I don't think people should boycott playable games just because they are not equal or superior to PS4, I do support waiting and complaining for games such a Bladestorm and Toukidden for being graphically unplayable, for DOA5 to not have online and/or taking too long to get it, which may or may not kill the number of players, and stuff like that, but if the game has full content, is playable, and has the same equivalent price (PS3 port games for PS3 prices, PS4 terrible ports should not be at PS4 price...), that should not be an exclusively bad thing.
