Do you hear Castlevania series organs? While we wait for Konami to make a move to resurrect it, you may play a Castlevania Chronicles II Simon's Quest for PC by Warmachine Studios. It is a remake of Castlevania II: Simon's Quest for Nintendo.
Below you can see a sneak peek at the start trailer, which touts a very impressive piece of art (considering that the author will earn nothing but praise as a prize... as long as Konami does not block his game).
Simon's Quest: A Scaricare Castlevania Chronicles II
The soundtrack may be downloaded here.
The most essential aspects of the game should be reported: the ability to earn hearts without having to enter a check; completely new levels, all with their own bosses; the return of the ax and cross as secondary weapons; controller compatibility; FMV cutscenes; and more.
Play it, because it's worth it (and you'll never pay anything to do it).
