I love this game and I despise this game, and more often than not I despise it, and I'll tell you why:
I'm a very logically-minded thinker, prone to coming up with new strategies to counter my past mistakes, and I never have any trouble with RPGs unless the situation I'm in is unwinnable (for instance, getting into a fight without mid-combat equipment switching against a big wind team with all wind weak characters - this is an example, and I've never actually done something that stupid). You know how Atlus games are reputed to be incredibly difficult? I don't find them a cakewalk, but after the first few levels I completely stop dying (except against their persistent habit of one-hit kill spells that work remarkably well for the enemies), and within a short time after that I don't find any of the fights frustrating. My point is, I'm very good at games of numbers.
Let me give you the generalities of my last day of play:
# of characters rolled: about 60
Average floors completed per character: two and some spare change.
fraction of preventable deaths (I had some manner of avoiding the death, but didn't utilize it, by extension, all other deaths I exhausted everything in my power to survive): about 1/3rd
Read that last line again.
Yes, only one in three of my deaths was actually preventable. Generally, those preventable deaths were overconfidence (level five warrior being beaten to death by a hobgoblin,) or refusal to use up my escape routes on an unworthy fight (a teleport scroll in the above situation).
Mummy Summoners, one of my favorites, my general strategy is to skip Sticks to Snakes, because I rarely find /anything/ suitable for conversion in the time it takes to reach level three and learn the much more reliable Call Imp. Out of about ten Mummy Summoners, only three actually earned Call Imp
Of those three:
A previous summoner (spriggan, I think) had shown me that learning Summon Scorpions doesn't end well, so I tried the other one. So this mummy learnt Summon Elemental next. This spell is basically impossible to utilize when you first learn it, which I only discovered posthumously (trying to run away from an air elemental, the second of two castings of the spell, both of which turned out hostile).
The next utilized Call Imp liberally, having found a ring which gave them another 6? MP, but teleported into a horde of orcs
The last stuck to Summon Small Mammals, as it starts to become a viable spell around the same time Call Imp does, but ended up being chased across five floors by a group of hobgoblins, jackals, quokka, etc. Summoned Small Mammals whenever they became available. Was finally taken out when she ran headlong into Beogh's Smite.
All others died within the first two floors, generally due to unreasonably large hordes of enemies (which seem to be common when you're a summoner?)
Another common example is (high-physical-bonus race, such as Kenku/Minotaur/Ghoul/Troll) Monk. These guys made up a large chunk of my play today, and exactly zero lived to so much as see the Ecumenial Temple. Monks, you'll recall, generally don't have anything they can use in a fight except their fists and whatever potions or scrolls they find. Therefore, if you run out of those things trying to find a way to finish or escape a fight, your death was NOT preventable.
My other favorite class is Transmuters. Few live to learn Evaporate.
Lastly, I refuse to utilize Berserkers, because I find their gameplay tedious. Yes, someone who utilized summoners, transmuters, and monks finds /Berserkers/ tedious.
I guess what I'm getting at is, the early levels don't require skill - there's nothing you can do about the vast majority of your deaths, and it gets, well, tiresome. Now, don't misunderstand me, I've had several characters reach the Orcish Mines and get several floors into them or skip them for going further into the main dungeon. I don't /always/ die in the early levels, but it's too often to make those brief forays deeper worth the time.
