Green_Hilltop: The first two Dracula games are fun. The second one is a mix of puzzles and HO though, so beware if you don't like HOs. The first one is a pure puzzle/adventure game though with inventory management and actual 3D FMVs. Don't play the last three games though, they were made by a different publisher and imho, the story sucks. 
  It could be a difference of opinion or it could be that you're getting the two series of games mixed up (it is confusing).  
 The Frogware games: 
 - Dracula Origin (2008) 
 - Dracula: Love Kills (2011) - as you say it's more of a HOG than a genuine adventure game  
 The Microids games: 
 - Dracula: The Resurrection (1999) 
 - Dracula: The Last Sanctuary (2000) 
 - Dracula 3: The Path of the Dragon (2008) 
 These 3 are sold as the 'Dracula Trilogy' on GOG. The first two look good but the game play is fairly average, whereas the third is regarded by many as being the best of the Dracula games. 
 - Dracula 4&5 (2013) - made by a different studio and generally poorly regarded.  
 Word of warning on the Microids games: 
 The GOG versions are the 'proper' versions of these games but the versions on steam are based on the bastardized ipad versions with reduced game play.
