A coworker gave me his Diablo III Ultimate Evil ed for Xbox360 to try out. I spent 2-3 evenings with it and just completed Act IV. I haven't touched Act V/RoS yet.
I like mobility and I wanted a challenge. A brief glance at the various guides up at th emoment seems to indicate Wizard is the omgwtfbbq op, followed by witch doctor/barbarian/crusader in any order you like, followed by demon hunter and monk so far down the tier list half the people didn't even bother adding it. Demon Hunter on expert seemed to fit the bill. I wasn't allowed to increase it any further since I hadn't completed Act IV or hit lv60 on my blind run. The game was laughably easy, although to be fair I only played on "expert" so maybe it gets better. But any game that requires you to complete it to unlock a difficulty above banalshiteasy can go fuck itself.
Once Act iV was over I had died 0 times and used a grand total of 12 health potions. My coffers were overflowing with cashmoney, crafting materials, potions and gems. I ran a probably terribly inefficient build. From level 30 onwards it looked pretty much like this:

Main source of damage was rapid fire with the slow rune and the passive that did extra damage to slowed shit. I swapped strafe out with venegance a few times for passive damage while I spammed rapid fire. Either worked, really. Between rapid flire slow, caltrop slow and evasive fire/strafe/regular dodge shenanigans I could strafe all day, except for the one or two encounters I met teleport+waller minibosses.
The actual combat was 'k. it had good "kinesthetics" as Grunker would call it. Powers felt fun to use and enemies came in a steady stream. If only there had been more elites and enemies had moved faster it would be quite enjoyable. I only played DH to high levels, so I can't say for the other classes. Monk felt a bit meh (made it to 20). Controller and your base attack making you teleport to enemy made my dude backflip all over the place into dumb spots. Maybe it's better with mouse. Wizard made it to around level 15 before I got really tired of the voice actress. It seemed to be even easier than demon hunter though. If I get dragged into playing this in BRO-op I will probably try out crusader. All in all it seemed like every class got some decently entertaining abilities. (Although I miss the skill trees from earlier incarnations). Speaking of BRO-op, the Konsoletard version of D3 allows multiple players on the same screen a la gauntlet. It could be an ok beer&pretzles game I think.
The game fell flat in 3 areas though.
1: The maps. Aesthetics aside - I preferred the gothic feel of D1, but D3 is still better than D2's clusterfuck - the layouts are too linear. The more complex geometries of the individual map segments don't allow them to be put together in as many configurations as the previous games. While D1 managed relatively believable indoor architecture with rooms and corridors, everything in D3 is some zig-zag corridor of rooms with very little rhyme or reason in the layout. The variety of environments was nice though, so plusses for that. There was (I think) 3-4 different dungeon tilesets per act, including exteriors.
2: The monsters. Having the same monster recolored and renamed to save memory and disc space was acceptable when D1 came out. It's not 'k today. All the way to the end, I met the same recolored monsters from act 1 with new names but the same attack patterns. There were a few new additions per act, but the majority of your kills are rehashes from earlier.
3: The items. Oh boy, that's the big one. Diablo (and especially diablo 2) had some very good loot generation going on. Possibly some of the best randomly generated loot in any game. Diablo 3 goes full monty haul however and it hurts the in-game "economy" as it were. I haven't checked out the AH (no such thing on my chipped console). But from around level 10 onward, my Demon hunter did not even bother looking at the stats of magical equipment. There's a tooltip with ratings (damage, defense, other) rated from 3 red arrows down to 3 green arrows up whenever you pick up an item. Anything that was rare or legendary with damage boost got equipped, everything else got immediately marked as trash. There are 3 vendors in town, but I soon learned to ignore them entirely. The shit they sold was always worse than the rares that dropped every 2-3 minutes while murdering shit. And you get so much gold there's no reason to sell your loot either. All loot you aren't currently wearing goes directly to the blacksmith for salvage into crafting materials. The blacksmith can pump out laughably cheap rares as long as you feed him junk weapons. And he can pump them out at the level and type you like and keep pumping them out until you get the stats you want on them. 95% of the gear I used he made for me. I miss going over the new stuff the merchants had back in Tristram and having to decide if I wanted to spend gold. Or sinking excess lucre into the gambling vendor for unidentified items that may or may not turn out to be set items and legendaries.
So yeah. the game was not as bad as I had feared, but it turne dout to be decidedly average. And while the combat is decent (but too easy), the game misses all the things that I thought made Diablo 1 and 2 great.
