Not everything you can do with a Berserker you can do with a Maceman
Big & Small mapscript has tons of islands, and getting most of those is an important strategy to stay below domination limit but max out cities. I think amphibious units and navigation promoted ships could be really nice there. Also, I chose Ragnar partly for his traits and starting techs. He is FIN which still find one of the strongest traits for a Sushi-Economy. I have a huge problem with growing my cottages, the first ones usually go online at about 1500 BC, then FIN makes a huge difference. Then, Ragnar starts out with Hunting, which is very good if you play with GHs, you get at least twiced as many and have even higher chances for a free tech. Bad side is, that he cannot find BW in a Hut, but something like AH is also fine. Fishing isn't too bad either if you specifically look for coastal starts, something you really wanna have on this map, as conquering coastal cities to settle the islands simply takes too long, and Seafood gives Commerce, good Commerce with FIN. I think I will try Oracle CS or at least Oracle Machinery again with what I've learned about overlap and ressource-sharing. But maybe it'll all come down to good old Oracle Currency, which is just so powerful.
And I like UUs really really really, but I'm not obsessed with them. I'm seriously thinking about playing Shaka and simply go for Elepult, which imo is a superstrong strategy. Praets have the problem that they cannot fight Maces, War-Elephants don't have that problem, they become obsolete with pikes and that's a lot later. Maces though are my favourite unit of all, I won Replay #1 nearly completely with CR-Maces, together with Trebs, they beat anything up to Rifling with nearly no losses. That's why I thought, why not try out a unique Mace that gets nice Bonuses which fit the map, before going back to Shaka and Elepult again.
Numidians were just a detour because everybody says HAs are just so great and I wanted to try those out, I wasn't impressed by them. Praets are great, but Maces have a longer lifespan and come just at the right moment. Conqs I'm gonna try out at some time because I remember Cuirrassiers to have been really strong sometimes, but that won't be any time soon because Izzy's Traits and starting Techs suck just so much and her UB doesn't fit at all, who even builds Castles. You see, a UU alone is not enough for me.
@ Habitus: The "Scientist-Thing" I never understood, which is one of the problems I have with my actual games. I usually get the first GS way too late, sometimes past CS, because I simply don't get up a Library really early, and evn if I have one, I seldomly find the Food to work Specialists. I found it easy with Hatty because of CRE-discount, but with normal leaders, a Library is 270 Hammers on Marathon. If one builds Settlers / Workers, a Granary and Oracle before that, that's easily over 1500 Hammers, then there are no Forrests with which one could fasten up a Library, and whipping it is normally no solution on my maps, because it's really hard to find enough food to support those Gold Mines. Maybe it's again easier with less Settlers / Cities.
