InvaderZ reminds me of Paranoia in many ways, and not just the use of clones. It most certainly is made to be played for laughs, sorta a "beer & pretzels" RPG. Reading it has been a blast, and I expect running it would be too, but I have some quibbles.
I'm not going to complain that the PDF wasn't spruced up with hyper-texting or such, as it's only $1.99 for 118 pages. It would, however, been nice to have a table of contents. It's a pain to flip thru a PDF, especially when you don't know where you are trying to flip to. The character generation rules are tucked somewhere in the middle, and it took me a bit to find the task resolution bits and pieces. I like to jump around as a reader, even my first read thru, and this was made difficult without a table ot contents or an index.
All that aside, if it plays have as well as it read, this would be a blast to run at a convention or a Game Day (one off) type of real life setting. Fast paced and funny. Just isn't so fast to navigate the PDF.
