For the record, somehow Asmor's quote of me got attributed to Cadfan, and he had nothing to do with it.
Your logic seems to be:
Magic has many cards which can counter spells.
These cards are powerful.
D&D 3rd edition was designed by the same company which makes Magic.
Skipped step: "After M:tG had proven itself to be a popular product."
D&D 3rd edition has more options for countering spells than previous editions.
Therefore, Magic inspired D&D's increase in counter spelling.
Add to this that in almost every other dedicated FRPG (IOW, non-toolkit RPG like HERO or GURPS), counterspelling- if it exists- is largely skill driven, not spell driven. 3Ed's counterspelling explicitly requires either Dispel Magic or casting the same spell that is being cast (or an extremely similar one, if you have the Improved Counterspell feat). The only skill comes in identifying the spell to be countered.
This means that, just like in M:tG, you can only counterspell if you have the correct spell at your disposal.
Since counterspelling is spell driven, counterspelling attempts may also be countered. Again, much like M:tG.
Counterspelling also occurs regardless of the relative power of the spellcasters. Fireball counters Fireball, even if the attacker is 20th level and the defender is 6th, assuming the defender makes his Spellcraft check. In M:tG, only a few counterspells take into account the relative power of the spells or condition of the "Wizard"- countering works if the effects resolve. Most other systems have a mechanic by which a more powerful caster's spells are virtually uncounterable by lesser beings.
Yes, it
is an inference, but hardly a stretch.
