Zero was REDICULOUSLY hard. I couldn't get by ANY of the first levels.
ZX... I really liked it, but Model L was useless, F was boring, P was ONLY good for kunai spam, and H was only useful for certain things. Z was the best, obviously.
Classical....never played it much...only 7. Which was....decent.
Never played Legends. Ever. 'Capt for ONCE at my friends house.
X. Meh~ I Don't really like it when they make the "Second of the original"...But I love Zero. Hell, just check out my name. I like both versions of Zero, but the second ones much cooler. ^__^
EXE....I only started at 4, so all of them were virtually the same to me. at least 5 had the liberation... but they were basically the same. But I was still suckered into all three of the latter ones.
And lastly, Star Force.
No.
Just no.
3D Exe? Don't work.
Here's me list:
1. Zero
2. Classic
3. ZX
4. EXE
5. X
6. Legends
7. Star Force
