Meh, mark should be 2... 5 is an accident.
I will be brief.
I only have 4.5 years experience as a programmer, of those only 1.5 were spent on C++ and I have no experience whatsoever in game programming;
the new stuff I learned from this book could be printed on a letter page or less.

This is just generic, and rather primitive, data structures and algorithms book, that applies them to making a small game instead of usual example search/whatever programs. Sometimes it feels like a data structure was used merely as an example that fit in that place in grand example-place matching, and not as the most useful or efficient one...

One could probably turn it into "Data Structures for Database Server Programmers", "Data Structures For Embedded Device Programmers", or "Data Structures For Solving World Hunger" with copy/paste and minor grammatical corrections ;)
