Something youre going to have to realize now is that melee and brawl are similar in a lot of ways but they are also very different in a lot of ways. To start wifi is awful, there is drastic lag on your inputs when you play online, making the online metagame much different from the offline, lagless, metagame. So dont play wifi, find people to play with in real life. I also hope you know that if you play melee on a widescreen tv your inputs will lag so dont do that, and if you dont have component cables for your wii brawl will lag on a widescreen tv. Youre the safest playing on a crt tv, almost 100% of the time there is no lag. Back to the whole playing both games thing. Brawl is going to be much easier to pick up than melee will be, for brawl is a much less technical game. Brawl is rather slow compared to melee. Also a lot of technical advanced techniques that existed in melee didnt carry over to brawl, things such as wavedashing, jump cancel grabs, crouching out of dash, shielddashing, moonwalking, shai dropping, waveshining, and the biggest one that got taken out was L - Canceling which made SHFFLing possible. Although that was a robust list those are not the only existing Advanced Techniques that exist in melee that didnt carry over to brawl. Some generalizations about differences between the games exist as well. One thing is brawl is a much more defensive game than melee is. In brawl shield stun is much lower than than shield stun in melee. The shield stun is so low in brawl that it actually gives the defender the advantage most of the time when they get attacked in shield. Also hitstun in brawl is much lower than melee, meaning that there are very few true combos unless your comboing someone at a low percent, or you could just play metaknight and have plenty of true combos. The ledge acts very differently in brawl than it does in melee. In brawl you dont grab the ledge...the ledge grabs you, meaning that every character can grab the ledge facing away from it, up b's auto sweetspot, and the range at which your character can grab the ledge has been extended. Lastly the physics are very different from brawl to melee. In brawl the physics are much floatier, characters live much longer in general than characters live in melee which gave birth to the fact that in the competitive brawl ruleset you play 3 stocks while in melee you play 4 stocks. Idk im going to stop here and let me know if you have questions or whatever.
