Well why would i even create this topic if i didn't have any ideas of my own; so here they are!
First of all i just have to say that i have been completely satisfied with Bethesda's last three game's. i play them so frequently i hardly ever play anything else and it's really weird when you realized months have gone by. literally. fallout 3 has have to be without a shadow of doubt the best RPG ever created in history. although that's arguable, because most Bethesda fans are playing skyrim too. but when bethesda start's work on Fallout 4 here's what they should have:
* Up to four player co-op. Why? This would be awesome, imagine roving the wasteland with your pal's! i promise, if fallout 4 has this in the game it could help bridge the gap between multiplayer lover's to RPG's. Hopefully they don't do what Borderlands or Dead Island did. That was an epic fail. i just felt like they weren't the experience i was looking for. They should have separate quest's for Co-op and separate quest for when it's just one player. this way players get the same authenticate experience during the main quest but still another enjoyable experience when playing with friend's. i'm sure you all have your reason's too.
*XBOX 720. Yes even if Bethesda makes a fallout 4 it will be on the '720' most likely. also im not the first to say this and im pretty sure there was leaked information as well.
*Gun's! Fallout has a record of having a ton of weapons to choose from, not to mention different one's depending on your play style. although the customization has been great, why not make it even better. it's simple, just give us more.
*Player customization. make it larger and bigger of course. perhaps even playable species like ghouls or super mutants to even vampires or cyborg. anything really
*World size. with the '720's' engine you should be able to make the world 20x bigger or even more.
*Bigger! just make every thing bigger.
So that conclude's my list; but what's your's?
