I thought I would copy it here from PM if anyone else is interested.
OK. I dunno which kind of emulators Mac has, so I just name a couple of titles. From older consoles to newer ones.
Genesis: Shining Force 1-2. RPG/Tactics with AWESOMELY beautiful cartoonish graphics. Just take a look: https://www.youtube.com/watch?v=E1MCLMRKklQ (skip to battle scene, about 2:00). There’s a remake of Shining Force 1 for GBA called Shining Force: Ressurection of the Dark Dragon with even better graphics and some additional content, you may check this one instead. More RPG than tactics, but a pretty and interesting one.
SNES: Der Langrisser. Tactics/RPG with highly nonlinear plot (just check this plot graph O_o: https://gamefaqs.gamespot.com/snes/588277-der-langrisser/faqs/48923). Deep tactical combat with Rock-Paper-Scissors-Lizard-Spock-… mechanics. RPG element involves promoting your commanders, that will result in them being able to hire different units. Even more interesting, you can promote some warrior commanders into level 2 wizards than level 3 warriors which will result in them being able to cast some spells, while packing a punch. Promoting is nonlinear - you have several options at each level. And the list of commanders you get (each with his own upgrade tree) depends on the plot path you choose, so replayability is vast.
GBA. Of all fire emblem games I played my favourite is Fire Emblem: Sacred Stones on GBA. Can’t say much about it, overall decent tactics. Can’t say that the series is the best happened to me in all my gaming life, but it is a good game.
There’s also a remake of Shinning Force I already mentioned.
PSP: Valkyria Chronicles 3. Only in Japanese…but there’s fan made english patch out there. Very special game, Turn Based Tactics + Third Person Shooter in one special brew. Characters are very awesome, plot is also good.
Saturn: Shining Force 3, parts 1,2,3. The first part was officially released in ENG, other 2 are fan translated. Same as the Shining Force 1-2 in idea, but with some nice additional mechanics. What is that part 1,2,3 stuff is about, you ask? In each part you play through mostly the same story but from the different sides of conflicts. Decisions made in Part 1 make some events in Parts 2 and 3 different, Part 2 also influences Part 3. These are 3 different games, so you will have to load save file from the previous one into the next. All three are playable standalone though, but I see no reason to play part 3 without ever playing parts 1 and 2.
I have to go for now, I may continue later. Tell me what you think, I wonder if you found anything I proposed interesting enough.
There’s also Langrisser 4 (fan translated) for PS1 or 2, don’t remember, which is arguably superiour to SNES Der Langrisser, but has a bit less complex plotline. Graphics and gameplay is better, though.
Oh and also Final Fantasy Tactics Advance on GBA and Advance 2 on Nintendo DS. I like the second title more. Childish graphics and plot, but a very good game
