Exist any kind of mini games inside any one of the Grand Theft Auto games that is basically a miniature variation of an older GTA title?
There are nonetheless IIRC areas you can reach in GTA : San Andreas that take you to surprise maps from earlier video games.
No, I do not assume so. There were mini video games in san andreas (gallery, wagering etc) and also in gta4 (swimming pool, bowling, darts) yet none in fact permitted you to play GTA inside GTA :)
GTA and also GTA2 are readily available as free downloads if you simply intend to play them!
