Best OG character to date Replay gave you alternate routes with remixed stages instead of yet another "pick othe route" routine REALLY long especially by handheld standards Good animation, perhaps the most fluid animation since RKO on GBA GREAT music Best Masquerade Epic cast Read Japanese for perhaps one of the most brilliant crossover stuff when it comes to using story essence as their core. This is the game that basically inspired the modern story One of the best srw despite difficulty issue
Negative would be bugs. These bugs did not stop people from playing Z2-2 where a simmilar and as deadly effective bug exists both affecting money. And SP bug which need some foreknowledge and coincidence to use.... So.... Not that much of an issue
Difficulty is to put it simply surprisingly good at beggining, and has nice enough flow until part 2. To be exact the game is moderate at first, plenty at Part 1 finale, moderate at the start of part 2, and drop after Tekkaman Hiver is given to you. After this, maybe only like an ecounter with a specific og enemy is a challenge, and then there's the damned Ankoku Daishogun
Why yes, this game is separated in two parts
Stages with infinite reinforcements are prominent, including infamously infinite Wufei and Baron Ashura
There are A LOT of duel maps, IIRC W has the most amount of duel events out of any SRW including a last stand duel near the end of the game
I think its one of the srw where listing why you shouldn't play it is harder than why you should
Tl;dr its easy, only like R is easier and K if you abuse the hell out of the game. Still a must play SRW. Period.
A better question might be whether there are any reasons NOT to play it, and honestly I can't think of any. It's got an excellent series list, great integration of the various plotlines (including many fun cross-series moments), excellent original story and characters, and great animation for a handheld. Honestly, W is pretty much everything that SRW is about - compared to that, lack of voices really doesn't matter.
On a side note, I've recently been replaying this, and had totally forgotten about a certain long-haired pilot playing dress up. Cracked me up all over again. XD
