1. I seem to remember BG ends after you kill the final boss. I request that this not happen. Let me tromp around the Sword Coast as long I want please. Or at least until I stumble on a quest that leads to my whole party getting kidnapped in the night which would . . .
2. . . . transition BG1 into BG2 better. It would also be nice if BG1 somehow kept track of character defining moments, such as NPC deaths or romance arcs, for BG2 and ToB to recall and reflect. (Also let us keep our hard earned gear in BG2, or at least let us find the people Jon sold it all to.)
SUPER BONUS REQUEST: This suggestion is for way down the line, but I personally loved the mods that let me go back to BG1 maps from BG2. I'd love to see enhanced BG2 and ToB released as giant DLC for BG1, basically just making the world bigger. Since there's already going to be new quests, reaching BG2 could unlock a few high level quests in BG1 areas, and reaching ToB could unlock even more in both BG1 and BG2 areas (once you're able to get back to them).
I don't play RPG's to beat RPG's. I go on quests to beat quests. The Game Over moment is a punishment. Replace it with a reward: a sandbox. Let us, at the very least, just wander around the land we saved/dominated.
EDIT: So far no substantial responses to my main points, and I think that's mostly my fault for including this last part. It should have gone to the post-ship thread if anywhere. To clarify my second request: if the devs are going to make new content for BGEE and are considering making BG2EE, I hope this time around the things players do with the new content, at the very least, will be remembered in BG2EE. I can't imagine anyone thinking that growing attached to a new NPC only to see that NPC get killed off or disappear without explanation in a second game would be a good thing -- plenty of instances like this with how the original games were handled.
I'm afraid my first request is going to be forever lost in the mix. My fault for not keeping to one request per post I suppose.
