Of course its possible to come up with Hundreds of effects and possibilities, but thats all they are, Possibilities I had the same feeling about Oblivion for alot of things, now I'm only working with whats been stated, and in your example why make potions to augment the character temporarily when Attributes do that just fine?
why actually yes I can detail a significant portion of people who have come and gone from Bethesda, not all of course but its not like this is a secret, and even that doesn't change the fact that Bethesda -is not- the same bethesda from years ago, because just as people come and go, people change, concepts change, games change thats easy to see from Daggerfall to Oblivion, do I want them to do exactly like prior games? no, but I do expect them to improve upon the -good- old games brought to the table, people say Skyrim will be Skyrim, but Skyrim would not be Skyrim if Oblivion wanst Oblivion and morrowind Wasnt Morrowind Ad Arena, 5 years isnt left completely to the Engine, you think every soul was working on Dragons for 2 years? errm no Skyrim was the first time they probably took a hard look at Attributes from 4 games running and thought erp lets get rid of them?
Actually attributes is a given in role playing games, and I admire them for looking at them closely this time and trying to figure out a new system, it's not bad to try a new system, you're asking yourself "How it can be done?" but I'm pretty sure that if it didn't work they wouldn't have implemented it, take Todd's grasp on horses for example. Todd said that they won't implement horse riding unless it's done well. So what does that tell you? They could always do what was in Oblivion, you know... the HORRIBLE HORRIBLE horse riding system...
As for your first statement: Attributes didn't do it just fine, and that's why they got rid of them. You have to admit it was a pretty bad system they had with the attributes in Oblivion. If they looked at it closely and told themselves that in order for it to work they have to remove them, then it probably fits with the game and the rest of the game. Like I said, if it didn't work well, they wouldn't have implemented it.
Another thing Bethesda admitted to was that they made mistakes. Not only in Oblivion, but in Skyrim too. They said they used the new radiant story system for almost anything, but then they took a step backwards and saw that it doesn't fit. Now they're using in a good, controlled and measurable way. It's obvious they're thinking HARD about this game, you can't deny it.
As for your second statement: It's obvious they're a different company, that's a given too. But making a statement like "hmm we are undoubtedly sixy, lets bring in more and put in as many cliche things as possible because..you know...it never fails" has (like I already said) absolutely no grounds at all. They changed, but I didn't see them making even ONE game that lacked depth and originality (except for Oblivion a little bit, but you saw what happened in FO3 all of a sudden), see my point?
They failed to disappoint me, although I did like Morrowind better, but when you actually see all the depth they're putting into this game, changing all the systems, trying new things, going to risky grounds (let's face it, they probably expected to have a wave of rage throughout the community after they'll publish they got rid of attributes), so why would they get rid of something that is known to be solid, and is already a known and popular system in RP games just so they could make money? Your statement has absolutely no logic at all, because if they did that only to make money, they wouldn't have gotten rid of attributes as it's an easier system to implement rather adding details gathered upon details gathered upon details of character development options. They'll have to think HARD to make each character unique if they would've gotten rid of attributes. Plus, they would've needed to create a whole new system for it, and nonetheless, a system that WORKS.
Fact is, you can't say that removing attributes is a move towards simplicity or making money because it's easier to implement attributes and they would've known it would create a killing frenzy amongst all their old fans (me included).
