I already saw a topic asking people if they prefer GTA San Andreas or GTA Vice City which is not exactly this topic's theme and I hesitate to unearth a topic that didn't receive any reply for 10 years so I prefer creating this one.
Now back to the core of the topic:
-Even if Vice City is a very agreable place it sometimes look as a golden jail compared to San Andreas. Nothing values this feeling of freedom you have when you can explore 3 cities plus the countryside and a desert.
-The bikes' handling is too rigid in Vice City and Tommy falls too oftenly, in SA the bikes' driving is smoother and when your skill reaches the maximum CJ falls much less oftenly
-You don't need to drive long distances to complete the paramedic job, by going in a small village you can do the job much more fastly making it nearly agreable.
-Although the cars handling regressed a lot compared to Vice City the codes to empty the streets, the nitro and the fact the cities aren't divided in islands makes the taxi job more entertaining in San Andreas
-The very good bikes handling, the fact you can perform the vigilante job on a bike, the codes to explode the enemies on touch and empty the streets, the alternations between cities coutryside and desert give this job a unique charm in SA
-Although they are more bonuses than anything else the ability to change CJ's body, tune cars, eat, practice fitness, learn various fighting styles, the huge quantity of cothes you can use, the ability to date with girlfriends and to swim add to the immersion and the gaming pleasure
-You can get rich from the game start with the Inside track and the Robois food mart and start buying all the houses and weapons you want, a good mean to discover some of the games' features very early.
-The safehouses aren't just nice buildings you can't visit, they have an interior and globally look like real houses. When you buy a rich house you really feel like someone rich and not like the owner of an empty nutshell filled with hallways.
-Contrary to the previous episodes you don't keep playing a greedy ruthless unlawful psychopathic killing-machine but a more human character who feels emotions, has qualms about doing some things and doesn't immediately know what he should do. Desppite some flaws this concept is globally well exploited and brings a welcome change.
-The gangs wars add a new dimension to the gunfights and are as good for those who love the dangerous fights as for those who want to make some areas more secure.
I probably forgot some things.
