Pros
Great people in the trenches, good two IP with perspectives for great games. Very good place to learn new things and improve your skill. In the end Warsaw is a really nice place to live. Pretty good salary for people from abroad, average for locals.
Cons
Typical flaws - middle management sucks and does not play any games. Talents are lost due to pressure, low salary or simple bullying or bad decisions. Long working hours, weekend work (sometimes paid sometimes not). Fake milestones just to increase the pressure. Company is on the Warsaw's stock exchange which creates additional pressure form the investors. Felt like a sect rather than a company. Bonus system is a joke - totally biased and rigged to reward middle management rather than the people that actually get the job done. Poor technology vision - programmers are usually a slaves to the rest of the team.
