Hi! I'm from Hungary. The first GTA I played was VC when I was 10. Since then Grand Theft Auto has been my all-time favourite video game series. My target is to complete every GTA game.
GTA games I've completed (the numbers after the the games show the order I completed the episodes of the series):
Grand Theft Auto - every missions  (great game, but the absence of the saving function is irritating, everything else is fine) GTA London '69 - every missions  (the same experience as with the GTA 1) Grand Theft Auto 2 - every missions  (it's hard to start a district, tough missions, KF-s are impossible, tokens are hard to obtain, but the gameplay similar to the 3D games) Grand Theft Auto III - 100%  (I'm disappointed with it, I thought it is as improved as VC, but the bikes, assets, weapons, helis, great rock music are missing which reduces the fun in the game) Grand Theft Auto: Vice City - 100%  (my personal favourite, everything is perfect, story, missions, music... except one thing the swimming...) Grand Theft Auto: San Andreas - 100%  (nearly as good as VC but there are too many unneccesary thing, clothes, barber, numerous pizza menus. Great landspace (big part of it is unused), too much ghetto) Grand Theft Auto IV - 100%  (good game, but it isn't as good as the GTA3 era games, something is missing from it which have the older ones (I don't know what it is) and I miss the colors too...) GTA The Lost and Damned  - 100% (A great expansion pack, which complements the IV's story, great new ideas) GTA The Ballad of Gay Tony  - 100% (same experience as with the TLaD, the main game with thes two DLC-s reached the the VC's and SA's level) Grand Theft Auto V - 100%  It was great!
I'll complete the rest of the series when I will have time:
GTA London '61 Grand Theft Auto Advance GTA Chinatown Wars GTA Liberty City Stories GTA Vice City Stories
My other favourite game from Rockstar Games is: Red Dead Redemption - I prefer it over GTA IV. Side missions, activities are great. Story is awesome.
