I'm not an expert but I would assume its probably due to the Wii being one the best setting consoles of all time with an established homebrew community. The WiiU was relatively poor selling,
Some games genuinely need a remake or remaster. Others... sure. Its an easy trap to fall into a lazy, double dipping mentality.
I would really like to see "bad" games get remakes. Ones that fix previous issues.
I really didn't like playing online against other people always felt like I was being matched against children... Sorry it's your 7th birthday but I guess I'm supposed to mow you down anyway...
I have reflexes a cat would be jealous of and a near psychic ability to read people, makes online play feel incredibly unfair. Ironically I have been booted from online servers for being a bot.... Or aim assist lol
