Hey Shigi! ^^
Thanks for the quick reply! I understand your problem. I've worked on a few RPG Maker 2000 projects a decade ago and from that I can extrapolate how huge projects must be like. You need to remember which switches and variables are needed for which tasks and why you programmed something like this and not like that. As a programmer I face this problem every now and then and if I didn't explain it in detail by using huge comments, then I start changing the code to what seems more efficient and when I'm 50% through I notice "oh so THAT's why I didn't do it like that." and then I backtrack. And THEN I write comments.

I went to your HP to check and found that the news you're referring to are from 16.10.2013, i.e. just 1 week before I asked. What a coincidence, after 2 years.

I like it when something like that happens.
What do you mean by "allowed me to continue working on it (and to keep the rights to it)"? Does the company theoretically have the right to forbid you to work on it and are they allowed to take away your rights? Is this about "you may not create products that are competitive to ours" or something?
But it was a good decision to leave a company which just fires a team that has developed a great and successful game like PvZ. That's so American.
Rakuen looks interesting. I'm looking forward to playing a game where a hospital is an actual hospital, in contrast to what you typically see in games like Outlast.

How much will it cost?
I am fine, thanks for asking. The two biggest changes in my life are:
1. I joined the German Pirate party, because chaos and transparency are the way to go to fight bribery and blackmail.
2. I became a Brony, because I love media with a positive atmosphere, if I get the feeling that the author loves his/her work and doesn't just do it for money.
