Don't want to sink 100+ hours into Fortunes Weave? Play this game. It's on NSO and can be finished in 30ish hours if you turn off its clunky battle animations. Ike is the series' best protagonist and its not even close. He starts out as a naive country boy and grows into a literal social justice warrior. He's basically John Brown with blue hair and a big ass, magical sword. If that doesn't sell you on the game, then nothing will.
Here are some things to know if you want to transfer information to Radiant Dawn (hopefully this will be possible on NSO):
Having an easy file on PoR will cause an error during transfer so play on normal (it's easy).
Max level characters in PoR will get a starting bonus to any stat they max out (+5 for HP, +2 for everything else)
Sothe is a special case and his stats will be carried directly over if they are higher than his RD starting stats (up to +6 in defense and resilience)
Ike and Soren need to have A-level support in PoR to unlock secret scenes in RD though this also requires a second of playthrough of RD and a few other annoying things like having Ike fight the Black Knight when he has no chance of winning and Soren attacking Micaiah which is only possible with Bolting.
