The "old" weapons are merely a fireball type thing which goes through enemies, and an ugly spinning grey thing which is like a strong blaster. In other words, they would have both been pretty useless in multiplayer. The new pepper spray is much more useful since it's hard to see and goes so fast, and the electro blaster is the best weapon for shooting through thick walls.

I prefer 1.23/1.24. It has online play, level editing, better level compression, better sound effects, better graphics, more logical weapons physics, better balanced weapons for multiplayer (yes, I know that seekers are the best weapon currently, but as for all the other weapons, they are equally useful in the hands of someone who knows how to use them properly aside from TNT and ice), better tilesets, better options (for example, theres no window mode in the OEM), stomping does 2 damage, there are more bosses, and finally, more events (such as snow).

The full version of this game is superior in almost every way. The OEM is only preferred by some people because it is a novelty.
