mushaden: I've started playing Age of Decadence and really enjoying that, so if I do revisit this game it will be after that.
My party
Fighter - Sword/Shield
Rogue - Dual Daggers
Vi and my own Valkyrie-guarding flanks
Priest - Mace/Shield, misses 90% of the time
Ranger w/ crossbow in the rear
Wizard - I have some status effect spells, but otherwise seems useless (in the center)
Also, I've tried playing Might and Magic World of Xeen, but it was a little too old school for me right now. Should I try a newer one?
Thanks for all the replies! I may try novice or cheating
Some thoughts:
If your fighter is missing to often, don't go Berserk. If your fighter is hitting consistently, go Berserk for more damage.
Priests become better at fighting if you boost their strength an dexterity. Make sure your Priest learns Armorplate and Magic Screen (in that order): Those two spells make a big difference and should be cast immediately after resting. (Note that you need them only on one character.)
For Mages, Missile Shield and Enchanted blade are the important spells that should be cast immediately after resting. Freeze Flesh and Noxious Fumes are particularly nice status spells. Fireball isn't as useful IMO. When you reach a high enough level, Summon Elemental comes in handy (but watch out when fighting enemies that can inflict Turncoat status). Also, try to max Intelligence so you get Power Cast. (If you haven't used the Trynton fountain yet, you can stop at 95 Intelligence and use the fountain to reach 100.)
If you can raise your Ranger's Alchemy to 15, you can have her start combining potions for money. Also, if you can recruit a Gadgeteer RPC, you can have him make a doubleshot crossbow for your Ranger. (Note that you will go through ammunition quite quickly with one, however.) If you decide to make a Gadgeteer for yourself, make her female so that she can wear the stamina regen necklaces you can find in Arnika's temple. (The same advice applies to bards as well.)
For a future playthrough, an alternative to a Mage is a Bishop. I would still advise those spell I mentioned (though note that in Arnika you can buy the Enchanted Blade spellbook, and I recommend conserving some spell picks for later with one).
Remember that Enchanted Blade, Missile Shield, Armorplate, and Magic Screen are actually only needed on one character each (though ideally that character should be a regular party member, not an RPC like Vi, because RPCs won't follow you everywhere).
For Bishops and pure casters (non-Priest), I recommend raising Speed alongside Intelligence so you can act sooner. (Senses also lets you act sooner, but its expert skill doesn't, though it would be good for your Ranger.)

Sarisio: You might try Might and Magic VI. Don't try MM 7, 8, 9 until you played MM 6. To be honest, MM 6 is one of the reasons why I couldn't get into Wizardry 8. MM 6 looks a bit like W8, but MUCH bigger (W8 is very small game actually, but it is padded by very slow battles and all the other wrong stuff), better and no level-scaling nonsense. Battles are also quite fluid unlike W8's slog, loot is much more interesting, and dungeons are much more exciting. Wizardry 8 might have better graphics, better looks, but that's basically it.
Wizardry 8, IMO, has better growth mechanics (skills increasing by use) and has more interesting classes as well (Bard and Gadgeteer come to mind).
