I’m definitely enjoying the game, including making out like a Bandit. (The Thieves’ Guild is rather easy, since this game has some of the stupidest guards in history and no security worth the name). However, I definitely have some problems with parts of it.
First, interaction is pretty marginal. NPC’s can say about four things, most of which are obvious and little of which matters. In fact, I’ve found only one real interaction, which was absolutely hilarious (Jarl Ravencrone throws a hilarious fit at a certain party), but which does leave me hungry for more. I keep thinking that while this games forms a great foundation and is fun to just enjoy, I can’t stop thinking about what kind of insane level of sheer awesome it would be if Obsidian then went in and polished it with more complexity, more dialogue, and character. Speaking of that party, the game makes it seem like you can stealth it, and then makes it almost impossible without invisibility. Obsidian would have made certain you could just hack your way though, sneak about and find out what you need by overhearing everything, free some captive monsters to kill guards and distract the rest, bribe your way into what you need, or just fast-talk yourself into the secret lair.
You can get married - but it’s meaningless. The NPC just follows you home, basically. You don’t really do anything and don’t really interact. Yes, it may sound corny, but where’s the romance? Even a blandly epic, Nordic romance? I’d be inclined to have marriage start an entire questline of its own.
I have not found Blackreach, and while I like the dungeon design overall, I definitely note it’s extremely linear. Dungeons are mostly just tubes, which annoy me. They’ve actually gone even more towards that irritation in Oblivion, although the dungeons are better in every other conceivable way, being much more believable and “organic” to the world.
I don’t mind the skill-based levelling, but some perks are “required” but really quite pointless, even an insult. Part of the problem is that some whole skills are really too specific. Yes, I like lockpicking, too. But it probably shouldn’t have a skill all its own. Same with pickpocket. Most skills in the game cover a wide array of actions, or at least a number of options and tricks. Some of the rest… not so much.
However, I will say that the level of storytelling is vastly improved, and kudos for that. Thus far, the Companions story is an epic tale of honor and courage overcoming all, the thieves are a tale of greed and treachery, and the main story, if a little short, is still darn good. I’m sure the others are no less worthy. I’m even tempted to start over just to begin playing a new character (question: can you absorb dragon souls and learn shouts if you don’t start the main quest?)
Other issues: to this day, they can’t get companion AI to walk right. OK, fine, but put in a teleport function so they just warp to you if you get lost. Is it perfect? No. But it’s a solution which lets the player get on with playing and not worrying about whether he’s lost his minion.
You need a giant fortress/home/playground. I don’t know why this is so hard for Bethsoft. They started the trend long ago, and still can’t figure out how to do it right. I’d be quite happy if you could hear about some old fortress ruin or whatever, go clear it out, and move in. Sure, renovating the place would cost a lot - and that’s part of the point. Give the player something to do. By the end they should have a large custom home, filled with their own servants, services, and even new quests to discover. Ideally, the decor should be customizable, with basements filled out like dungeons, dwemer ruins, or daedric temples, and towers built like ice caves or solid stone. Would also be nice to buy your own carriage (which would be like every other carriage, but cost nothing to ride and would look really fancy). And you could have a place for all your housecarls and so forth to live. Eventually, you could even have a trader who will buy anything and everything from you (at a huge discount, though).
