>>47625592>Is it too "late" for me to start?Depends of what you want. March had May and a horni bunni and that ain't coming back until next year.
Other than that you might struggle against some late game content because it's kinda designed around players with a year~ old account but were reachinh the 2nd year anniversary which will likely have a lot of goodies for everyone.
A lot of good shit is free, as well although the most important freebie may not come for a while (Xerneas).
