There really is no reason at all that the GBA should still be verboten on here. It's a natural fit for the board in nearly every way.
>It's a 2D focused handheld with a number of entries in or ports of /vr/ staple series that already get discussed on here anyway, meaning the rule is already loosely enforced with regards to it.
>It's old enough to have fallen out of popular discussion on 4chan and would thus be unlikely to attract many crossboarders. /v/ has maybe one thread about the console each week that reaches a cap of maybe 200~ replies and /vg/ users who frequently discuss its titles are both rare and likely post here already.
>It's already over sixteen years old and with the release of the Switch has now seen three new generations of Nintendo handhelds come out, putting it on par with the likes of the N64 and PS1.
>Is the final iteration of a /vr/ staple handheld line - the Gameboy family - and it being included would be a solid way to round out the bunch.
>When the Dreamcast got added it was in an exceedingly common position; infrequently discussed by other boards, part of the very early sixth gen for its type of console (home), the last member of its particular line, and home to many games that were already talked about on here anyway. Adding it in no way compromised the quality of the board in itself, and serves as proof that the GBA could theoretically be a fine fit for /vr/ as well.
At absolute worst we should unban it at the end of this console generation, by which point it'll be nearly at its second decade most likely, but I see no reason why it shouldn't have been allowed already with the dawn of the first eight generation handheld.
