im a big fan of morrowind and oblivion, but not once have i ever played aren or daggerfell...i dont think ive even seen a screenshot of them would you guys (or girls) recommend buying them? id kinda like to know a more in depth history of the elder scrolls series and i figure the best way is to play them all, but i dunno if its worth it. yay or nay?
Don't buy Arena, download it. It's available for free on the Elder Scrolls website. If you enjoy that, then by all means buy Daggerfall, because the odds that you'd enjoy Arena and not its sequel are next to nil.
If, on the other hand, you DON'T like Arena...well, the best I can do is tell you to try Daggerfall's Betony demo (Google "betony demo" without the quotations, you'll find it pretty quick). It's entirely representative of the actual game, so if you like it then it's a safe bet that you'll like Daggerfall and if you don't then the odds that you'd like the full game are extremely slim.
