Very first that I bought? Deus Ex. By that time I already played it quite a lot, but I felt that it deserves buying even though I didn’t have any income at that age. Looking back at that seems nostalgic. It had a proper manual and everything. It even seemed somehow “magical”, because as kids we weren’t really used to owning games (as in our “own” games, not just something borrowed from a friend which was usually just burnt on empty CD). Good times.
