I dont think that game is enough with "little time", if you rly want to get into it :D Im not playing it myself, but am watching it on youtube and it looks fun. A lot slower pace than your regular open world RPG, but it actually serves the game right. I havent played/watched first title, but from what iv seen so far, the "western spirit" is captured quite nicely and the atmosphere as well with how the world behaves and the relationships between the characters in the main group etc. it looks rly cool :)
The game is beautiful in all aspects both in terms of the scenario and the level of graphic detail. This game shows how the open-world to evolve in an amazing way. The 8 years of realization by Rockstar gave a good result.
