Recently I’ve noticed a small amount of comments in the music gaming industry that seem to target products or are used as negative pathways for debates.

Comments like “This game is like that game so it’s a rip off!”

But why?  What does this solve?  Is that the worst feedback you can come up with?
Why does this problem seem to specifically target the music game genre but not others?  When is the last time someone tried to prevent Unreal Tournament from existing after id Software’s Quake3?  What are your thoughts on this?

Let’s make some comparisons to these other titles.  (Past favorites –  2d side scrolling)

Super Mario Bros.  
Sonic the Hedgehog
Crash Bandicoot
Kirby’s Adventure  

Are these games similar?  Absolutely…  What’s your point?
Are they fun?  Yes …
Do they all have reasonable following?  Yep
Are they able to coexist in the market?  It seems so… I can’t remember the last time a fan of the Kirby series tried to make negative comparisons towards Mario Bros. for being “first” or being a similar type of game.
Did fans of Kerby try to prevent others from enjoying Crash Bandicoot?  No… Not at all.  Why would they?
With Regards to this issue, comparisons seem to be a common occurrence of debating and negative vocal ammunition towards products.  So what is the purpose?

For the small amount of people that prefer to sit back and do this (on private forums) by all means, have fun with that.   You can continue with this behavior as long as you like, but it won’t have an impact on the market or the sales numbers for a new product.  You don’t have to “like” a new product, but it seems silly for you to try to prevent others from enjoying something that they might enjoy.  You should consider offering constructive feedback that helps benefit the community and the products in the future.

This topic wasn’t directed towards a specific person/reference… It’s just a gentle reminder to not be so close minded towards new products that may (in your opinion) seem similar to others.  You should consider trying something before having a complete opinion.
