That link just made me feel all sort of stupid for buying 2 new pcs. Cant cancel them either as they are custom made. Well my fault for being stupid and not read up on the new engine first. Here is hoping they got it all perfect the first time around. It deffo detered me from even contemplating buying the uber edition. Maybe buy special edition second hand.
Well, if you play other games, it won't be a loss. It's never stupid to get a new rig if you feel it's time. It's a great investment if you are still playing DAO and if you play something like skyrim (not sure if you do). It will make for better gaming with those games.
I used an average PC for skyrim at first and then bought my gaming rig specifically for it. Honestly, that probably wasn't the brightest thing to do by some people's standards, but I got a good 900 more hours out of it, though at least 100 are from making mods and testing them. That's a lot of use and enjoyment. If you get part of that out of playing DAO on the computers, then it's worth it. You'll likely have better performance than you do with the current one, and there are probably other games in the future you might enjoy more as well, just not so much with DAI for modding, but it will run smoothly or smoother than it would on an older rig. So again, that is not really like it's a total loss. It's just that it won't be as beneficial as it would if we could mod.
I think someone from BW did say they haven't eliminated the idea of a toolset or something like it but in the same breath that it takes time and implied it wasn't likely to happen but the possibility of it happening wasn't a priority which seems to be how BW is on modding in general, which is a shame because modding would give them a chance to compete with skyrim in terms of allowing gamers more freedom and creativity.
As for which edition you get of DAI, I'd say it would be an utter waste to spend more on the game than it's really worth. Your plan sounds like a good one. Though I'm not sure if it's download or boxed. If it's boxed you could buy it used but I thought for PCs they had locked us into getting it through them which means not cheap.
