Hmm... Isn't there a movie coming out soon that has the same title and a similar theme? I don't want to be that project's creator when the lawyers smell the blood in the water...
This is Alex, the guy that made the deck. I actually researched that same thing, because although "pixels" is only one word and very generic, I was worried about that movie too.
I looked into it, and movie names can only be trademarked if they are sequels or series. The Pixels movie is based on a short french film made 2 or 3 years ago. So given how it's not a series and its not based on any book series - think harry potter, hunger games- it's in clear waters.
Also, all movies have to register with MPAA and new movies have to make sure they don't infringe on somebody's previous title, BUT this only applies to the film industry. So it's clear on that end as well.
Believe me, I did not want to be sued for any project, specially considering I'm not gonna make millions of off it lol I did my research, and made sure everything was good before starting the project!

I like this. The problem I have with most pixel art decks is that it's too self aware, this deck doesn't tip it's hat to itself tryng to say 'look at how pixel I am, isn't that trendy. look, I incorporated joysticks and neon colors because 80's, isn't that clever?'. This is keeping the fourth wall in tact, even if the execution isn't the best I think it is worth supporting just for that.
edit
*sees price per deck* HAHAHAHA, nevermind. Maybe I will make my own pixel deck.
Oh and sorry about the pricing Justin! I'm fairly new to the playing cards community and don't know if this matters, but they are going to be printed in 310mgs linen stock. Just recently upgraded it from the original stock being offered. So they will be looking pretty slick IMO, I'm receiving them soon, so I'll be posting pics. Anyways the pricing was based on what they charged me for this kind of stock, shipping costs, supplies, etc. I've seen other kickstarters charge less and others more for their decks, so I tried to be in the middle and offer the best quality possible for the price and goal.
