However I do have some fears about Skyrim:
1) Remember climbing mountains in Oblivion? Not fun was it? When traversing mountains you were almost forced to stay on preset paths, unless you had good acrobatics. Now look at what we know of Skyrim. It'll be full of jagged, steep, mountains of great size. If Bethesda doesn't add back the fly spell, or make some new ability to 'climb' things that are too steep to walk up, then Skyrim may prove to be a very tedious game indeed.
2) Crashing!!! At one point in Oblivion (I know I'm using a lot of Oblivion references, I've played the other games, Oblivion just applies the best.), when the Great Gate to Oblivion opens and monsters are streaming out, my game very neerly crashed. With the new draw distances, graphics, and everything else going on all at once, crashing it seems may be a huge issue. Even compacting then unzipping data to keep in managable doesn't work indefinately, eventually system limits will catch up with Bethesda. Lets hope they work this out!
3) My third and final concern is that Bethesda will make a game too much for the masses. The major difference between Oblivion and other TES games, is that Oblivion was a game designed to attract all kinds of players, while the other TES games were deep, immersive, and offered the greatest fun to hard-core RPGers. I'm one of those hard-core RPGers, and found Oblivion lacking in certain areas. My concern is that, Oblivion was designed for the masses, and was the biggest hit of all TES games. Bethesda may try to maximize the profitability of Skyrim by following the lead of Oblivion.
Adressing my 3rd concern, I admit that it is possible to develop a game for both the masses and those hard-core RPGers, but it will take some time and an active effort on the part of Bethesda's designers. So we can only hope that this is one of their focuses.
What do you guys think? Are my concerns legitimate, or do you think I'm totally wrong about how the game should be, or how it will be for that matter. What concerns do you have? What do you think will be the best part of Skyrim?
