1. Make Sure It Has Mod Support
This is the big one. Even if Rockstar doesn't add anything else on this list, mod support is a must, because if the game is structured in such a way that allows mods, all of these things and more can be added to the game for free. The great thing about mod support is that it allows players to fine-tune the game exactly to their tastes. If you fancy yourself a bit of a hardcore player, there's mods like "Big City Life" for
Grand Theft Auto IV that adds basic needs such as hunger and thirst, as well as an inventory system that weighs Niko down depending on how much he's carrying. The average player might not go for that, but the great thing about mod support is that theoretically, there's a mod for everyone. Whether you want more safehouses, better stability, more content, or just a stunningly-beautiful game, the modding community can accommodate players of any taste, making
Grand Theft Auto V the exact game you want it to be. Even if the PC port of this game ends up being terrible - and it very well could be - mod support can save the day. Here's hoping players will only need it to make a great game better, instead of fixing another lazy port.
